Pull misc vfs updates from Christian Brauner:
"Features:

- Reduce pipe->mutex contention by pre-allocating pages outside the
lock in anon_pipe_write().

anon_pipe_write() called alloc_page() once per page while holding
pipe->mutex. The allocation can sleep doing direct reclaim and runs
memcg charging, which extends the critical section and stalls any
concurrent reader on the same mutex. Now up to 8 pages are
pre-allocated before the mutex is taken, leftovers are recycled
into the per-pipe tmp_page[] cache before unlock, and any remainder
is released after unlock, keeping the allocator out of the critical
section on both sides. On a writers x readers sweep with 64KB
writes against a 1 MB pipe throughput improves 6-28% and average
write latency drops 5-22%; under memory pressure - when the cost of
holding the mutex across reclaim is highest - throughput improves
21-48% and latency drops 17-33%. The microbenchmark is added to
selftests.

- uaccess/sockptr: fix the ignored_trailing logic in
copy_struct_to_user() to behave as documented and the usize check
in copy_struct_from_sockptr() for user pointers, and add
copy_struct_{from,to}_bounce_buffer() and copy_struct_to_sockptr()
helpers for upcoming users (IPPROTO_SMBDIRECT, IPPROTO_QUIC).

- bpf: add a sleepable bpf_real_inode() kfunc that resolves the real
inode backing a dentry via d_real_inode(). On overlayfs the inode
attached to the dentry doesn't carry the underlying device
information; this is used by the filesystem restriction BPF program
that was merged into systemd.

- docs: add guidelines for submitting new filesystems, motivated by
the maintenance burden abandoned and untestable filesystems impose
on VFS developers, blocking infrastructure work like folio
conversions and iomap migration.

Fixes:

- libfs: set SB_I_NOEXEC and SB_I_NODEV by default in init_pseudo()
and drop the now-redundant assignments in callers. This began as a
one-line dma-buf fix for a path_noexec() warning; a pseudo
filesystem has no reason not to set SB_I_NOEXEC. All init_pseudo()
callers were audited: the only visible effect is on dma-buf where
SB_I_NOEXEC silences the warning.

- Handle set_blocksize() failures in legacy filesystems (bfs, hpfs,
qnx4, jfs, befs, affs, isofs, minix, ntfs3, omfs). Mounting a
device with a sector size > PAGE_SIZE crashed roughly half of them;
the rest had the same missing error handling pattern. Plus a
follow-up releasing the superblock buffer_head when setting the
minix v3 block size fails.

- mount: honour SB_NOUSER in the new mount API.

- fs/fcntl: fix a SOFTIRQ-unsafe lock order in fasync signaling by
switching the process-group paths of send_sigio() and send_sigurg()
from read_lock(&tasklist_lock) to RCU, matching the single-PID
path.

- vfs: add an FS_USERNS_DELEGATABLE flag and set it for NFS, fixing
delegated NFS mounts (fsopen() in a container with the mount
performed by a privileged daemon) that broke when non-init
s_user_ns was tied to FS_USERNS_MOUNT.

- selftests/namespaces: fix a hang in nsid_test where an unreaped
grandchild kept the TAP pipe write-end open, a waitpid(-1) race in
listns_efault_test, and a false FAIL on kernels without listns()
where the tests should SKIP.

- filelock: fix the break_lease() stub signature for
CONFIG_FILE_LOCKING=n.

- init/initramfs_test: wait for the async initramfs unpacking before
running; the test and do_populate_rootfs() share the parser state.

- fs/coredump: reduce redundant log noise in
validate_coredump_safety().

- iomap: pass the correct length to fserror_report_io() in
__iomap_write_begin().

- backing-file: fix the backing_file_open() kerneldoc.

Cleanups:

- initramfs: refactor the cpio hex header parsing to use hex2bin()
instead of the hand-rolled simple_strntoul() which is reverted, and
extend the initramfs KUnit tests to cover header fields with 0x
prefixes.

- Replace __get_free_pages() and friends with kmalloc()/kzalloc()
across quota, proc, ocfs2/dlm, nilfs2, nfs, nfsd, libfs, jfs, jbd2,
isofs, fuse, select, namespace, configfs, binfmt_misc, bfs, and the
do_mounts init code - part of the larger work of replacing page
allocator calls with kmalloc().

- Use clear_and_wake_up_bit() in unlock_buffer() and
journal_end_buffer_io_sync() instead of open-coding the sequence.

- Drop unused VFS exports: unexport drop_super_exclusive(), remove
start_removing_user_path_at(), and fold __start_removing_path()
into start_removing_path().

- fs/read_write: narrow the __kernel_write() export with
EXPORT_SYMBOL_FOR_MODULES().

- vfs: uapi: retire octal and hex constants in favor of (1 << n) for
the O_ flags. Finding a free bit for a new flag across the
architectures was needlessly hard with the mixed bases.

- dcache: add extra sanity checks of dead dentries in dentry_free()
via a new DENTRY_WARN_ONCE() that also prints d_flags.

- iov_iter: use kmemdup_array() in dup_iter() to harden the
allocation against multiplication overflow.

- fs/pipe: write to ->poll_usage only once.

- vfs: remove an always-taken if-branch in find_next_fd().

- dcache: use kmalloc_flex() for struct external_name in __d_alloc().

- namei: use QSTR() instead of QSTR_INIT() in path_pts().

- sync_file_range: delete dead S_ISLNK code.

- Comment fixes: retire a stale comment in fget_task_next() and fix
assorted spelling mistakes"

selftests/pipe: add pipe_bench microbenchmark

Add a small selftest that stresses pipe->mutex contention by spawning N
writer threads that hammer a single pipe with multi-page writes, plus M
reader threads that drain. Each writer records its own write() latency
samples into a log2-bucketed histogram; main aggregates and prints
total writes, throughput, average and percentile (p50/p99) latencies,
and the maximum observed latency.

Pass --memory-pressure to fork stress-ng (--vm 4 --vm-bytes 80%
--vm-method all) for the duration of the run, so alloc_page() in
anon_pipe_write() routinely hits direct reclaim. The flag fails
fast if stress-ng is not on $PATH.

Program print something like the following, for different writes,
readers, msgsizes and memory pressure:

config: writers=X readers=Y msgsize=Z duration=3 pipe_size=1048576
memory_pressure=[no|yes]
writes: total=54451 rate=18150/s
throughput_MBps: 1134.40

lat_p50_ns_upper: 262143

selftests: Deescalate error reporting

Commit 7e47389142b8 ("selftests: Preserve subtarget failures in
all/install") updated the propagation of errors from indivdual kselftest
targets to be similar to that seen with FORCE_TARGETS. While it would
be really nice to be in a position to do this currently it is premature
to do this as the default behaviour.

At present we default to trying to build all selftests but a combination
of code quality issues and build dependencies mean that it is almost
certain that at least one of them will fail to build (for example,
several depend on clang so don't work in a GCC container) and a top
level failure in the kselftest build reported. Further, the resulting
failures mean that the install target does not run at all so any build
problem is escallated to a complete failure to produce a kselftest
tarball so CI systems that run into issues loose all selftests coverage.
This has been causing disruption to a range of CI systems including
KernelCI, mine and Arm's internal one.

Revert the commit, users who need this behaviour should be able to use
FORCE_TARGETS for the time being. At present users that do this (such
as linux-next) are most likely building a subset of targets known to
succeed in their environments.

Merge tag 'vfs-7.1-rc1.mount.v2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs mount updates from Christian Brauner:

- Add FSMOUNT_NAMESPACE flag to fsmount() that creates a new mount
namespace with the newly created filesystem attached to a copy of the
real rootfs. This returns a namespace file descriptor instead of an
O_PATH mount fd, similar to how OPEN_TREE_NAMESPACE works for
open_tree().

This allows creating a new filesystem and immediately placing it in a
new mount namespace in a single operation, which is useful for
container runtimes and other namespace-based isolation mechanisms.

This accompanies OPEN_TREE_NAMESPACE and avoids a needless detour via
OPEN_TREE_NAMESPACE to get the same effect. Will be especially useful
when you mount an actual filesystem to be used as the container
rootfs.

- Currently, creating a new mount namespace always copies the entire
mount tree from the caller's namespace. For containers and sandboxes
that intend to build their mount table from scratch this is wasteful:
they inherit a potentially large mount tree only to immediately tear
it down.

This series adds support for creating a mount namespace that contains
only a clone of the root mount, with none of the child mounts. Two
new flags are introduced:

- CLONE_EMPTY_MNTNS (0x400000000) for clone3(), using the 64-bit flag space
- UNSHARE_EMPTY_MNTNS (0x00100000) for unshare()

Both flags imply CLONE_NEWNS. The resulting namespace contains a
single nullfs root mount with an immutable empty directory. The
intended workflow is to then mount a real filesystem (e.g., tmpfs)
over the root and build the mount table from there.

- Allow MOVE_MOUNT_BENEATH to target the caller's rootfs, allowing to
switch out the rootfs without pivot_root(2).

The traditional approach to switching the rootfs involves
pivot_root(2) or a chroot_fs_refs()-based mechanism that atomically
updates fs->root for all tasks sharing the same fs_struct. This has
consequences for fork(), unshare(CLONE_FS), and setns().

This series instead decomposes root-switching into individually
atomic, locally-scoped steps:

fd_tree = open_tree(-EBADF, "/newroot", OPEN_TREE_CLONE | OPEN_TREE_CLOEXEC);
fchdir(fd_tree);
move_mount(fd_tree, "", AT_FDCWD, "/", MOVE_MOUNT_BENEATH | MOVE_MOUNT_F_EMPTY_PATH);
chroot(".");
umount2(".", MNT_DETACH);

Since each step only modifies the caller's own state, the
fork/unshare/setns races are eliminated by design.

A key step to making this possible is to remove the locked mount
restriction. Originally MOVE_MOUNT_BENEATH doesn't support mounting
beneath a mount that is locked. The locked mount protects the
underlying mount from being revealed. This is a core mechanism of
unshare(CLONE_NEWUSER | CLONE_NEWNS). The mounts in the new mount
namespace become locked. That effectively makes the new mount table
useless as the caller cannot ever get rid of any of the mounts no
matter how useless they are.

We can lift this restriction though. We simply transfer the locked
property from the top mount to the mount beneath. This works because
what we care about is to protect the underlying mount aka the parent.
The mount mounted between the parent and the top mount takes over the
job of protecting the parent mount from the top mount mount. This
leaves us free to remove the locked property from the top mount which
can consequently be unmounted:

unshare(CLONE_NEWUSER | CLONE_NEWNS)

and we inherit a clone of procfs on /proc then currently we cannot
unmount it as:

umount -l /proc

will fail with EINVAL because the procfs mount is locked.

After this series we can now do:

mount --beneath -t tmpfs tmpfs /proc
umount -l /proc

after which a tmpfs mount has been placed beneath the procfs mount.
The tmpfs mount has become locked and the procfs mount has become
unlocked.

This means you can safely modify an inherited mount table after
unprivileged namespace creation.

Afterwards we simply make it possible to move a mount beneath the
rootfs allowing to upgrade the rootfs.

Removing the locked restriction makes this very useful for containers
created with unshare(CLONE_NEWUSER | CLONE_NEWNS) to reshuffle an
inherited mount table safely and MOVE_MOUNT_BENEATH makes it possible
to switch out the rootfs instead of using the costly pivot_root(2).

selftests/fsmount_ns: add missing TARGETS and fix cap test

Add missing top-level kselftest TARGETS entries for empty_mntns and
fsmount_ns so that 'make kselftest' discovers and runs these tests.

Fix requires_cap_sys_admin test which always SKIPped because fsopen()
was called after enter_userns(), where CAP_SYS_ADMIN in the mount
namespace's user_ns is unavailable. Move fsopen/fsconfig before fork so
the configured fs_fd is inherited by the child, which then only needs to
call fsmount() after dropping privileges.

selftests: Preserve subtarget failures in all/install

Track failures explicitly in the top-level selftests all/install loops.

The current code multiplies `ret` by each sub-make exit status. For
example, with `TARGETS=net`, the implicit `net/lib` dependency runs after
`net`, so a failed `net` build can be followed by a successful `net/lib`
build and reset the final result to success.

Set `ret` to 1 on any non-zero sub-make exit code and keep it sticky, so
the top-level make returns failure when any selected selftest target
fails.

netconsole: selftests: Move netconsole selftests to separate target

This patch moves netconsole selftests from drivers/net to its own target
in drivers/net/netconsole.

This change helps saving some resources from CI since tests in
drivers/net automatically run against real hardware which are not used
by netconsole tests as they rely solely on netdevsim.

lib_netcons.sh is kept under drivers/net/lib since it is also used by
bonding selftests. Finally, drivers/net config remains unchanged as
netpoll_basic.py requires netconsole (and does leverage real HW testing).

selftests/liveupdate: add userspace API selftests

Introduce a selftest suite for LUO. These tests validate the core
userspace-facing API provided by the /dev/liveupdate device and its
associated ioctls.

The suite covers fundamental device behavior, session management, and the
file preservation mechanism using memfd as a test case. This provides
regression testing for the LUO uAPI.

The following functionality is verified:

Device Access:
Basic open and close operations on /dev/liveupdate.
Enforcement of exclusive device access (verifying EBUSY on a
second open).

Session Management:
Successful creation of sessions with unique names.
Failure to create sessions with duplicate names.

File Preservation:
Preserving a single memfd and verifying its content remains
intact post-preservation.
Preserving multiple memfds within a single session, each with
unique data.
A complex scenario involving multiple sessions, each containing
a mix of empty and data-filled memfds.

Note: This test suite is limited to verifying the pre-kexec functionality
of LUO (e.g., session creation, file preservation). The post-kexec
restoration of resources is not covered, as the kselftest framework does
not currently support orchestrating a reboot and continuing execution in
the new kernel.
