Mon, 17 Aug 2026 22:57:04 +0200

Merge tag 'vfs-7.3-rc1.super' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfsPull vfs superblock updates from Christian Brauner: - Make it possible to share a block device between multiple filesystems. erofs can mount read-only blob devices shared between many superblocks, but because we only tracked a single superblock a freeze, thaw, removal or sync on such a device was never propagated to all the superblocks using it, and there was no way to find them. Add an efficient table to lookup all superblocks using a given block device. - A bunch of pre-existing fixes fell out of this work: A block-device freeze racing a btrfs device change could leave the whole filesystem stuck frozen. A bdev_freeze() issued by "dmsetup suspend" or an LVM snapshot resolves that holder to freeze the filesystem. and bdev_thaw() resolves it again to thaw. A freeze landing while btrfs is adding, removing or replacing a device freezes the filesystem. The membership change then drops that link. So the matching thaw could no longer find the superblock. Forbid freezing a device for the duration of a membership change, modelled on deny_write_access()/allow_write_access().* tag 'vfs-7.3-rc1.super' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (24 commits) super: fix dying superblock warning messages block: reject block device inodes with i_rdev == 0 in lookup_bdev() selftests/filesystems: add ustat() coverage fs: look up the superblock via the device table in user_get_super() super: make fs_holder_ops private f2fs: open via dedicated fs bdev helpers erofs: open via dedicated fs bdev helpers fs: tolerate per-superblock freeze errors on shared devices fs: look up superblocks via the device table in fs_holder_ops ext4: open via dedicated fs bdev helpers btrfs: open via dedicated fs bdev helpers xfs: port to fs_bdev_file_open_by_path() fs: add dedicated block device open helpers for filesystems fs: maintain a global device-to-superblock table ocfs2: don't reset s_dev on dismount ext4: use anonymous devices for KUnit test superblocks fs, block: move blk_mode_t and fop_flags_t into super: take lock after last reference count super: convert s_count to refcount_t s_passive btrfs: deny freezing devices undergoing a replace ...

d943e68edc5cb98192d38e31373bb6b6a73230c6 - selftests/filesystems: test O_TMPFILE creation on idmapped mounts

Mon, 15 Jun 2026 14:52:19 +0200

selftests/filesystems: test O_TMPFILE creation on idmapped mountsAdd a regression test for the fsuidgid_has_mapping() check invfs_tmpfile(). It idmaps a detached tmpfs mount so that thecaller-visible id range [0, 10000) maps onto the on-disk range[10000, 20000) and checks that: - a caller whose fsuid/fsgid fall outside that range cannot create an O_TMPFILE through the mount and gets -EOVERFLOW instead of an inode owned by (uid_t)-1; - a mapped caller can create an O_TMPFILE, link it into the namespace, and the ownership round-trips through the mount idmap: it is reported as 0 through the mount and stored as 10000 on the underlying tmpfs.The test runs entirely as root and uses setfsuid()/setfsgid() to becomethe unmapped caller, so it needs no helper user. The layer directory isworld-writable so that an unmapped caller still clears the directorypermission check and reaches the fsuidgid_has_mapping() test.Link: https://patch.msgid.link/20260615-work-idmapped-tmpfile-v1-2-754a94d81f83@kernel.orgReviewed-by: Jan Kara Signed-off-by: Christian Brauner (Amutable) List of files: /linux/tools/testing/selftests/filesystems/.gitignore

Tue, 16 Jun 2026 16:08:34 +0200

selftests/filesystems: add ustat() coverageuser_get_super() is now backed by the global device-to-superblock tableinstead of a walk of the super_blocks list. ustat(2) is its most directuser-visible consumer but nothing in the tree exercises it.Add a small regression test: the device number of a mounted tmpfs (ananonymous device, registered in the table by sget_fc()) must resolve,it must stop resolving after the unmount (the entry is dropped again inkill_super_notify()), and bogus device numbers keep reporting EINVAL.The test passes on kernels before the conversion: it pins down thesemantics the table-backed lookup must preserve.Link: https://patch.msgid.link/20260616-work-super-bdev_holder_global-v2-18-7df6b864028e@kernel.orgSigned-off-by: Christian Brauner (Amutable) List of files: /linux/tools/testing/selftests/filesystems/.gitignore

aab154a442f9ba2a08fc130dbc8d178a33e10345 - selftests: add file SLAB_TYPESAFE_BY_RCU recycling stressor

Mon, 21 Oct 2024 13:54:46 +0200

selftests: add file SLAB_TYPESAFE_BY_RCU recycling stressorAdd a simple file stressor that lives directly in-tree. This will createa bunch of processes that each open 500 file descriptors and then useclose_range() to close them all.Concurrently, other processes read /proc//fd/ which rougly does f = fget_task_next(p, &fd); if (!f) break; data.mode = f->f_mode; fput(f);Which means that it'll try to get a reference to a file in anothertask's file descriptor table.Under heavy file load it is increasingly likely that the other task willmanage to close @file and @file will be recycled due toSLAB_TYPEAFE_BY_RCU concurrently. This will trigger various warnings inthe file reference counting code.Link: https://lore.kernel.org/r/20241021-vergab-streuen-924df15dceb9@braunerSigned-off-by: Christian Brauner List of files: /linux/tools/testing/selftests/filesystems/.gitignore
