Merge tag 'for-5.15-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"The highlights of this round are integrations with fs-verity and
idmapped mounts, the rest is usual mix of minor improvements, speedups
and cleanups.
There are some patches outside of btrfs, namely updating some VFS
interfaces, all straightforward and acked.
Features:
- fs-verity support, using standard ioctls, backward compatible with
read-only limitation on inodes with previously enabled fs-verity
- idmapped mount support
- make mount with rescue=ibadroots more tolerant to partially damaged
trees
- allow raid0 on a single device and raid10 on two devices,
degenerate cases but might be useful as an intermediate step during
conversion to other profiles
- zoned mode block group auto reclaim can be disabled via sysfs knob
Performance improvements:
- continue readahead of node siblings even if target node is in
memory, could speed up full send (on sample test +11%)
- batching of delayed items can speed up creating many files
- fsync/tree-log speedups
- avoid unnecessary work (gains +2% throughput, -2% run time on
sample load)
- reduced lock contention on renames (on dbench +4% throughput,
up to -30% latency)
Fixes:
- various zoned mode fixes
- preemptive flushing threshold tuning, avoid excessive work on
almost full filesystems
Core:
- continued subpage support, preparation for implementing remaining
features like compression and defragmentation; with some
limitations, write is now enabled on 64K page systems with 4K
sectors, still considered experimental
- no readahead on compressed reads
- inline extents disabled
- disabled raid56 profile conversion and mount
- improved flushing logic, fixing early ENOSPC on some workloads
- inode flags have been internally split to read-only and read-write
incompat bit parts, used by fs-verity
- new tree items for fs-verity
- descriptor item
- Merkle tree item
- inode operations extended to be namespace-aware
- cleanups and refactoring
Generic code changes:
- fs: new export filemap_fdatawrite_wbc
- fs: removed sync_inode
- block: bio_trim argument type fixups
- vfs: add namespace-aware lookup"

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
