Merge tag 'for-6.2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
"This round there are a lot of cleanups and moved code so the diffstat
looks huge, otherwise there are some nice performance improvements and
an update to raid56 reliability.

User visible features:

- raid56 reliability vs performance trade off:
- fix destructive RMW for raid5 data (raid6 still needs work): do
full checksum verification for all data during RMW cycle, this
should prevent rewriting potentially corrupted data without
notice
- stripes are cached in memory which should reduce the performance
impact but still can hurt some workloads
- checksums are verified after repair again
- this is the last option without introducing additional features
(write intent bitmap, journal, another tree), the extra checksum
read/verification was supposed to be avoided by the original
implementation exactly for performance reasons but that caused
all the reliability problems

- discard=async by default for devices that support it

- implement emergency flush reserve to avoid almost all unnecessary
transaction aborts due to ENOSPC in cases where there are too many
delayed refs or delayed allocation

- skip block group synchronization if there's no change in used
bytes, can reduce transaction commit count for some workloads

Performance improvements:

- fiemap and lseek:
- overall speedup due to skipping unnecessary or duplicate
searches (-40% run time)
- cache some data structures and sharedness of extents (-30% run
time)

- send:
- faster backref resolution when finding clones
- cached leaf to root mapping for faster backref walking
- improved clone/sharing detection
- overall run time improvements (-70%)

Core:

- module initialization converted to a table of function pointers run
in a sequence

- preparation for fscrypt, extend passing file names across calls,
dir item can store encryption status

- raid56 updates:
- more accurate error tracking of sectors within stripe
- simplify recovery path and remove dedicated endio worker kthread
- simplify scrub call paths
- refactoring to support the extra data checksum verification
during RMW cycle

- tree block parentness checks consolidated and done at metadata read
time

- improved error handling

- cleanups:
- move a lot of code for better synchronization between kernel and
user space sources, split big files
- enum cleanups
- GFP flag cleanups
- header file cleanups, prototypes, dependencies
- redundant parameter cleanups
- inline extent handling simplifications
- inode parameter conversion
- data structure cleanups, reductions, renames, merges"

btrfs: use cached state when looking for delalloc ranges with fiemap

During fiemap, whenever we find a hole or prealloc extent, we will look
for delalloc in that range, and one of the things we do for that is to
find out ranges in the inode's io_tree marked with EXTENT_DELALLOC, using
calls to count_range_bits().

Since we process file extents from left to right, if we have a file with
several holes or prealloc extents, we benefit from keeping a cached extent
state record for calls to count_range_bits(). Most of the time the last
extent state record we visited in one call to count_range_bits() matches
the first extent state record we will use in the next call to
count_range_bits(), so there's a benefit here. So use an extent state
record to cache results from count_range_bits() calls during fiemap.

This change is part of a patchset that has the goal to make performance
better for applications that use lseek's SEEK_HOLE and SEEK_DATA modes to
iterate over the extents of a file. Two examples are the cp program from
coreutils 9.0+ and the tar program (when using its --sparse / -S option).
A sample test and results are listed in the changelog of the last patch
in the series:

1/9 btrfs: remove leftover setting of EXTENT_UPTODATE state in an inode's io_tree
2/9 btrfs: add an early exit when searching for delalloc range for lseek/fiemap
3/9 btrfs: skip unnecessary delalloc searches during lseek/fiemap
4/9 btrfs: search for delalloc more efficiently during lseek/fiemap
5/9 btrfs: remove no longer used btrfs_next_extent_map()
6/9 btrfs: allow passing a cached state record to count_range_bits()
7/9 btrfs: update stale comment for count_range_bits()
8/9 btrfs: use cached state when looking for delalloc ranges with fiemap
9/9 btrfs: use cached state when looking for delalloc ranges with lseek
