Merge tag 'for-6.17-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
"A number of usability and feature updates, scattered performance
improvements and fixes. Highlight of the core changes is getting
closer to enabling large folios (now behind a config option).

User visible changes:

- update defrag ioctl, add new flag to request no compression on
existing extents

- restrict writes to block devices after mount

- in experimental config, enable large folios for data, almost
complete but not widely tested

- add stats tracking duration of critical section in transaction
commit to /sys/fs/btrfs/FSID/commit_stats

Performance improvements:

- caching of lookup results of free space bitmap (20% runtime
improvement on an empty file creation benchmark)

- accessors to metadata (b-tree items) simplified and optimized,
minor improvement in metadata-heavy workloads

- readahead on compressed data improves sequential read

- the xarray for extent buffers is indexed by denser keys, leading to
better packing of the nodes (50-70% reduction of leaf nodes)

Notable fixes:

- stricter compression mount option parsing

- send properly emits fallocate command for file holes when protocol
v2 is used

- fix overallocation of chunks with mount option 'ssd_spread', due to
interaction with size classes not finding the right chunk
(workaround: manual reclaim by 'usage' balance filter)

- various quota enable/disable races with rescan, more verbose
notifications about inconsistent state

- populate otime in tree-log during log replay

- handle ENOSPC when NOCOW file is used with mmap()

Core:

- large data folios enabled in experimental config

- improved error handling, transaction abort call sites

- in zoned mode, allocate reloc block group on mount to make sure
there's always one available for zone reclaim under heavy load

- rework device opening, they're always open as read-only and delayed
until the super block is created, allowing the restricted writes
after mount

- preparatory work for adding blk_holder_ops, allowing device
freeze/thaw in the future

Cleanups, refactoring:

- type and naming unifications (int/bool, return variables)

- rb-tree helper refactoring and simplifications

- reorder memory allocations to less critical places

- RCU string (used for device name) refactoring and API removal

- replace all remaining use of strcpy()"

btrfs: add btrfs prefix to is_fstree() and make it return bool

This is an exported function and therefore it should have a 'btrfs_'
prefix, to make it clear it's btrfs specific, avoid future name collisions
with code outside btrfs, and make its naming consistent with most other
btrfs exported functions.

So add a 'btrfs_' prefix to it and make it return bool instead of int,
since all we need is to return true or false.

Merge tag 'for-6.16-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
"Apart from numerous cleanups, there are some performance improvements
and one minor mount option update. There's one more radix-tree
conversion (one remaining), and continued work towards enabling large
folios (almost finished).

Performance:

- extent buffer conversion to xarray gains throughput and runtime
improvements on metadata heavy operations doing writeback (sample
test shows +50% throughput, -33% runtime)

- extent io tree cleanups lead to performance improvements by
avoiding unnecessary searches or repeated searches

- more efficient extent unpinning when committing transaction
(estimated run time improvement 3-5%)

User visible changes:

- remove standalone mount option 'nologreplay', deprecated in 5.9,
replacement is 'rescue=nologreplay'

- in scrub, update reporting, add back device stats message after
detected errors (accidentally removed during recent refactoring)

Core:

- convert extent buffer radix tree to xarray

- in subpage mode, move block perfect compression out of experimental
build

- in zoned mode, introduce sub block groups to allow managing special
block groups, like the one for relocation or tree-log, to handle
some corner cases of ENOSPC

- in scrub, simplify bitmaps for block tracking status

- continued preparations for large folios:
- remove assertions for folio order 0
- add support where missing: compression, buffered write, defrag,
hole punching, subpage, send

- fix fsync of files with no hard links not persisting deletion

- reject tree blocks which are not nodesize aligned, a precaution
from 4.9 times

- move transaction abort calls closer to the error sites

- remove usage of some struct bio_vec internals

- simplifications in extent map

- extent IO cleanups and optimizations

- error handling improvements

- enhanced ASSERT() macro with optional format strings

- cleanups:
- remove unused code
- naming unifications, dropped __, added prefix
- merge similar functions
- use common helpers for various data structures"

Merge tag 'for-6.14-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
"User visible changes, features:

- rebuilding of the free space tree at mount time is done in more
transactions, fix potential hangs when the transaction thread is
blocked due to large amount of block groups

- more read IO balancing strategies (experimental config), add two
new ways how to select a device for read if the profiles allow that
(all RAID1*), the current default selects the device by pid which
is good on average but less performant for single reader workloads

- select preferred device for all reads (namely for testing)
- round-robin, balance reads across devices relevant for the
requested IO range

- add encoded write ioctl support to io_uring (read was added in
6.12), basis for writing send stream using that instead of
syscalls, non-blocking mode is not yet implemented

- support FS_IOC_READ_VERITY_METADATA, applications can use the
metadata to do their own verification

- pass inode's i_write_hint to bios, for parity with other
filesystems, ioctls F_GET_RW_HINT/F_SET_RW_HINT

Core:

- in zoned mode: allow to directly reclaim a block group by simply
resetting it, then it can be reused and another block group does
not need to be allocated

- super block validation now also does more comprehensive sys array
validation, adding it to the points where superblock is validated
(post-read, pre-write)

- subpage mode fixes:
- fix double accounting of blocks due to some races
- improved or fixed error handling in a few cases (compression,
delalloc)

- raid stripe tree:
- fix various cases with extent range splitting or deleting
- implement hole punching to extent range
- reduce number of stripe tree lookups during bio submission
- more self-tests

- updated self-tests (delayed refs)

- error handling improvements

- cleanups, refactoring
- remove rest of backref caching infrastructure from relocation,
not needed anymore
- error message updates
- remove unnecessary calls when extent buffer was marked dirty
- unused parameter removal
- code moved to new files

Other code changes: add rb_find_add_cached() to the rb-tree API"

btrfs: selftests: add delayed ref self test cases

The recent fix for a stupid mistake I made uncovered the fact that we
don't have adequate testing in the delayed refs code, as it took a
pretty extensive and long running stress test to uncover something that
a unit test would have uncovered right away.

Fix this by adding a delayed refs self test suite. This will validate
that the btrfs_ref transformation does the correct thing, that we do the
correct thing when merging delayed refs, and that we get the delayed
refs in the order that we expect. These are all crucial to how the
delayed refs operate.

I introduced various bugs (including the original bug) into the delayed
refs code to validate that these tests caught all of the shenanigans
that I could think of.
