Merge tag 'for-6.11-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
"The highlights are new logic behind background block group reclaim,
automatic removal of qgroup after removing a subvolume and new
'rescue=' mount options.

The rest is optimizations, cleanups and refactoring.

User visible features:

- dynamic block group reclaim:
- tunable framework to avoid situations where eager data
allocations prevent creating new metadata chunks due to lack of
unallocated space
- reuse sysfs knob bg_reclaim_threshold (otherwise used only in
zoned mode) for a fixed value threshold
- new on/off sysfs knob "dynamic_reclaim" calculating the value
based on heuristics, aiming to keep spare working space for
relocating chunks but not to needlessly relocate partially
utilized block groups or reclaim newly allocated ones
- stats are exported in sysfs per block group type, files
"reclaim_*"
- this may increase IO load at unexpected times but the corner
case of no allocatable block groups is known to be worse

- automatically remove qgroup of deleted subvolumes:
- adjust qgroup removal conditions, make sure all related
subvolume data are already removed, or return EBUSY, also take
into account setting of sysfs drop_subtree_threshold
- also works in squota mode

- mount option updates: new modes of 'rescue=' that allow to mount
images (read-only) that could have been partially converted by user
space tools
- ignoremetacsums - invalid metadata checksums are ignored
- ignoresuperflags - super block flags that track conversion in
progress (like UUID or checksums)

Core:

- size of struct btrfs_inode is now below 1024 (on a release config),
improved memory packing and other secondary effects

- switch tracking of open inodes from rb-tree to xarray, minor
performance improvement

- reduce number of empty transaction commits when there are no dirty
data/metadata

- memory allocation optimizations (reduced numbers, reordering out of
critical sections)

- extent map structure optimizations and refactoring, more sanity
checks

- more subpage in zoned mode preparations or fixes

- general snapshot code cleanups, improvements and documentation

- tree-checker updates: more file extent ram_bytes fixes, continued

- raid-stripe-tree update (not backward compatible):
- remove extent encoding field from the structure, can be inferred
from other information
- requires btrfs-progs 6.9.1 or newer

- cleanups and refactoring
- error message updates
- error handling improvements
- return type and parameter cleanups and improvements"

btrfs: remove objectid from struct btrfs_inode on 64 bits platforms

On 64 bits platforms we don't really need to have a dedicated member (the
objectid field) for the inode's number since we store in the VFS inode's
i_ino member, which is an unsigned long and this type is 64 bits wide on
64 bits platforms. We only need that field in case we are on a 32 bits
platform because the unsigned long type is 32 bits wide on such platforms
See commit 33345d01522f ("Btrfs: Always use 64bit inode number") regarding
this 64/32 bits detail.

The objectid field of struct btrfs_inode is also used to store the ID of
a root for directories that are stubs for unreferenced roots. In such
cases the inode is a directory and has the BTRFS_INODE_ROOT_STUB runtime
flag set.

So in order to reduce the size of btrfs_inode structure on 64 bits
platforms we can remove the objectid member and use the VFS inode's i_ino
member instead whenever we need to get the inode number. In case the inode
is a root stub (BTRFS_INODE_ROOT_STUB set) we can use the member
last_reflink_trans to store the ID of the unreferenced root, since such
inode is a directory and reflinks can't be done against directories.

So remove the objectid fields for 64 bits platforms and alias the
last_reflink_trans field with a name of ref_root_id in a union.
On a release kernel config, this reduces the size of struct btrfs_inode
from 1040 bytes down to 1032 bytes.

btrfs: remove location key from struct btrfs_inode

Currently struct btrfs_inode has a key member, named "location", that is
either:

1) The key of the inode's item. In this case the objectid is the number
of the inode;

2) A key stored in a dir entry with a type of BTRFS_ROOT_ITEM_KEY, for
the case where we have a root that is a snapshot of a subvolume that
points to other subvolumes. In this case the objectid is the ID of
a subvolume inside the snapshotted parent subvolume.

The key is only used to lookup the inode item for the first case, while
for the second it's never used since it corresponds to directory stubs
created with new_simple_dir() and which are marked as dummy, so there's
no actual inode item to ever update. In the second case we only check
the key type at btrfs_ino() for 32 bits platforms and its objectid is
only needed for unlink.

Instead of using a key we can do fine with just the objectid, since we
can generate the key whenever we need it having only the objectid, as
in all use cases the type is always BTRFS_INODE_ITEM_KEY and the offset
is always 0.

So use only an objectid instead of a full key. This reduces the size of
struct btrfs_inode from 1048 bytes down to 1040 bytes on a release kernel.
