Merge tag 'for-7.1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

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

- move shutdown ioctl support out of experimental features, a forced
stop of filesystem operation until the next unmount; additionally
there's a super block operation to forcibly remove a device from
under the filesystem that could lead to a shutdown or not if the
redundancy allows that

- report filesystem shutdown using fserror mechanism

- tree-checker updates:
- verify free space info, extent and bitmap items
- verify remap-tree items and related data in block group items

Performance improvements:

- speed up clearing first extent in the tracked range (+10%
throughput on sample workload)

- reduce COW rewrites of extent buffers during the same transaction

- avoid taking big device lock to update device stats during
transaction commit

- fix unnecessary flush on close when truncating empty files
(observed in practice on a backup application)

- prevent direct reclaim during compressed readahead to avoid stalls
under memory pressure

Notable fixes:

- fix chunk allocation strategy on RAID1-like block groups with
disproportionate device sizes, this could lead to ENOSPC due to
skewed reservation estimates

- adjust metadata reservation overcommit ratio to be less aggressive
and also try to flush if possible, this avoids ENOSPC and potential
transaction aborts in some edge cases (that are otherwise hard to
reproduce)

- fix silent IO error in encoded writes and ordered extent split in
zoned mode, the error was not correctly propagated to the address
space and could lead to zeroed ranges

- don't mark inline files NOCOMPRESS unexpectedly, the intent was to
do that for single block writes of regular files

- fix deadlock between reflink and transaction commit when using
flushoncommit

- fix overly strict item check of a running dev-replace operation

Core:

- zoned mode space reservation fixes:
- cap delayed refs metadata reservation to avoid overcommit
- update logic to reclaim partially unusable zones
- add another state to flush and reclaim partially used zone
- limit number of zones reclaimed in one go to avoid blocking
other operations

- don't let log trees consume global reserve on overcommit and fall
back to transaction commit

- revalidate extent buffer when checking its up-to-date status

- add self tests for zoned mode block group specifics

- reduce atomic allocations in some qgroup paths

- avoid unnecessary root node COW during snapshotting

- start new transaction in block group relocation conditionally

- faster check of NOCOW files on currently snapshotted root

- change how compressed bio size is tracked from bio and reduce the
structure size

- new tracepoint for search slot restart tracking

- checksum list manipulation improvements

- type, parameter cleanups, refactoring

- error handling improvements, transaction abort call adjustments"

btrfs: move shutdown and remove_bdev callbacks out of experimental features

These two new callbacks have been introduced in v6.19, and it has been
two releases in v7.1.

During that time we have not yet exposed bugs related that two features,
thus it's time to expose them for end users.

It's especially important to expose remove_bdev callback to end users.

That new callback makes btrfs automatically shutdown or go degraded
when a device is missing (depending on if the fs can maintain RW), which
is affecting end users.

We want some feedback from early adopters.

Merge tag 'for-6.20-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

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

- when using block size > page size, enable direct IO

- fallback to buffered IO if the data profile has duplication,
workaround to avoid checksum mismatches on block group profiles
with redundancy, real direct IO is possible on single or RAID0

- redo export of zoned statistics, moved from sysfs to
/proc/pid/mountstats due to size limitations of the former

Experimental features:

- remove offload checksum tunable, intended to find best way to do it
but since we've switched to offload to thread for everything we
don't need it anymore

- initial support for remap-tree feature, a translation layer of
logical block addresses that allow changes without moving/rewriting
blocks to do eg. relocation, or other changes that require COW

Notable fixes:

- automatic removal of accidentally leftover chunks when
free-space-tree is enabled since mkfs.btrfs v6.16.1

- zoned mode:
- do not try to append to conventional zones when RAID is mixing
zoned and conventional drives
- fixup write pointers when mixing zoned and conventional on
DUP/RAID* profiles

- when using squota, relax deletion rules for qgroups with 0 members
to allow easier recovery from accounting bugs, also add more checks
to detect bad accounting

- fix periodic reclaim scanning, properly check boundary conditions
not to trigger it unexpectedly or miss the time to run it

- trim:
- continue after first error
- change reporting to the first detected error
- add more cancellation points
- reduce contention of big device lock that can block other
operations when there's lots of trimmed space

- when chunk allocation is forced (needs experimental build) fix
transaction abort when unexpected space layout is detected

Core:

- switch to crypto library API for checksumming, removed module
dependencies, pointer indirections, etc.

- error handling improvements

- adjust how and where transaction commit or abort are done and are
maybe not necessary

- minor compression optimization to skip single block ranges

- improve how compression folios are handled

- new and updated selftests

- cleanups, refactoring:
- auto-freeing and other automatic variable cleanup conversion
- structure size optimizations
- condition annotations"

btrfs: allow mounting filesystems with remap-tree incompat flag

If we encounter a filesystem with the remap-tree incompat flag set,
validate its compatibility with the other flags, and load the remap tree
using the values that have been added to the superblock.

The remap-tree feature depends on the free-space-tree, but no-holes and
block-group-tree have been made dependencies to reduce the testing
matrix. Similarly I'm not aware of any reason why mixed-bg and zoned would be
incompatible with remap-tree, but this is blocked for the time being
until it can be fully tested.

btrfs: remove experimental offload csum mode

The offload csum mode was introduced to allow developers to compare the
performance of generating checksum for data writes at different timings:

- During btrfs_submit_chunk()
This is the most common one, if any of the following condition is met
we go this path:

* The csum is fast
For now it's CRC32C and xxhash.

* It's a synchronous write

* Zoned

- Delay the checksum generation to a workqueue

However since commit dd57c78aec39 ("btrfs: introduce
btrfs_bio::async_csum") we no longer need to bother any of them.

As if it's an experimental build, async checksum generation at the
background will be faster anyway.

And if not an experimental build, we won't even have the offload csum
mode support.

Considering the async csum will be the new default, let's remove the
offload csum mode code.

There will be no impact to end users, and offload csum mode is still
under experimental features.

btrfs: switch to library APIs for checksums

Make btrfs use the library APIs instead of crypto_shash, for all
checksum computations. This has many benefits:

- Allows future checksum types, e.g. XXH3 or CRC64, to be more easily
supported. Only a library API will be needed, not crypto_shash too.

- Eliminates the overhead of the generic crypto layer, including an
indirect call for every function call and other API overhead. A
microbenchmark of btrfs_check_read_bio() with crc32c checksums shows a
speedup from 658 cycles to 608 cycles per 4096-byte block.

- Decreases the stack usage of btrfs by reducing the size of checksum
contexts from 384 bytes to 240 bytes, and by eliminating the need for
some functions to declare a checksum context at all.

- Increases reliability. The library functions always succeed and
return void. In contrast, crypto_shash can fail and return errors.
Also, the library functions are guaranteed to be available when btrfs
is loaded; there's no longer any need to use module softdeps to try to
work around the crypto modules sometimes not being loaded.

- Fixes a bug where blake2b checksums didn't work on kernels booted with
fips=1. Since btrfs checksums are for integrity only, it's fine for
them to use non-FIPS-approved algorithms.

Note that with having to handle 4 algorithms instead of just 1-2, this
commit does result in a slightly positive diffstat. That being said,
this wouldn't have been the case if btrfs had actually checked for
errors from crypto_shash, which technically it should have been doing.
