Subject: [GIT PULL] Btrfs updates for 5.15
Date: Mon, 30 Aug 2021 15:18:39 +0200	[thread overview]
Message-ID: <cover.1630327914.git.dsterba@suse.com> (raw)

Hi,

the highlights of this round are integrations with fs-verity and
idmapped mounts, the rest is usual mix of minor improvements, speedups
and cleanups.

Please note there are some patches outside of btrfs, namely updating
some VFS interfaces, all straightforward and acked.

Please pull, thanks.

---
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
