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: enable large data folios for data reloc inode

For data reloc inodes, they are a special type of inodes that are not
exposed to user space, and are only utilized during data block groups
relocation.

They do not go under regular read-write operations, but have their file
extents manually created to have the same layout of a block group, then
its content is read from the original block group, and written back to
the new location which is in a new block group.

Previously all the handling was done in page units, and commit
c2832898126f ("btrfs: make relocate_one_page() handle subpage case")
changed the handling to subpage blocks.

On the other hand, data reloc inodes are a perfect match for large data
folios, as each relocation cluster represents one or more data extents
that are contiguous in their logical addresses.

This patch enables large folios for data reloc inodes by:

- Remove the special handling of data reloc inodes when setting folio
order

- Change relocate_one_folio() to return the file offset of the next
folio
Originally it's designed to handle fixed page sized blocks, but with
large folios, we can handle a large folio, thus we have to return the
end of the current folio.

- Remove the warning on folio_order()

- Use folio_size() to replace fixed PAGE_SIZE usage

- Use file_offset as iterator inside relocate_file_extent_cluster

btrfs: reloc: unconditionally invalidate the page cache for each cluster

Commit 9d9ea1e68a05 ("btrfs: subpage: fix relocation potentially
overwriting last page data") fixed a bug when relocating data block
groups for subpage cases.

However for the incoming large folios for data reloc inode, we can hit
the same situation where block size is the same as page size, but the
folio we got is still larger than a block.

In that case, the old subpage specific check is no longer reliable.

Here we have to enhance the handling by:

- Unconditionally invalidate the page cache for the current cluster
We set the @flush to true so that any dirty folios are properly
written back first.

And this time instead of dropping the whole page cache, just drop the
range covered by the current cluster.

This will bring some minor performance drop, as for a large folio, the
heading half will be read twice (read by previous cluster, then
invalidated, then read again by the current cluster).

However that is required to support large folios, and this gets rid of
the kinda tricky manual uptodate flag clearing for each block.

- Remove the special handling of writing back the whole page cache
filemap_invalidate_inode() handles the write back already, and since
we're invalidating all pages in the range, we no longer need to
manually clear the uptodate flags for involved blocks.

Thus there is no need to manually write back the whole page cache.

btrfs: remove btrfs_clear_extent_bits()

It's just a simple wrapper around btrfs_clear_extent_bit() that passes a
NULL for its last argument (a cached extent state record), plus there is
not counter part - we have a btrfs_set_extent_bit() but we do not have a
btrfs_set_extent_bits() (plural version). So just remove it and make all
callers use btrfs_clear_extent_bit() directly.

btrfs: don't print relocation messages from auto reclaim

When BTRFS is doing automatic block-group reclaim, it is spamming the
kernel log messages a lot.

Add a 'verbose' parameter to btrfs_relocate_chunk() and
btrfs_relocate_block_group() to control the verbosity of these log
message. This way the old behaviour of printing log messages on a
user-space initiated balance operation can be kept while excessive log
spamming due to auto reclaim is mitigated.

There are instances where strscpy() cannot be used such as where both
the source and destination are character pointers. In that instance we
can use sysfs_emit().

btrfs: use refcount_t type for the extent buffer reference counter

Instead of using a bare atomic, use the refcount_t type, which despite
being a structure that contains only an atomic, has an API that checks
for underflows and other hazards. This doesn't change the size of the
extent_buffer structure.

This removes the need to do things like this:

WARN_ON(atomic_read(&eb->refs) == 0);
if (atomic_dec_and_test(&eb->refs)) {
(...)
}

And do just:

if (refcount_dec_and_test(&eb->refs)) {
(...)
}

Since refcount_dec_and_test() already triggers a warning when we decrement
a ref count that has a value of 0 (or below zero).

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"
