Subject: [GIT PULL] Btrfs fixes for 6.11-rc4, part 2 From: David Sterba To: torvalds@linux-foundation.org Cc: David Sterba , linux-btrfs@vger.kernel.org, linux-kernel@vger.kernel.org Date: Sun, 18 Aug 2024 14:43:54 +0200 Hi, a few more fixes. We got reports that shrinker added in 6.10 still causes latency spikes and the fixes don't handle all corner cases. Due to summer holidays we're taking a shortcut to disable it for release builds and will fix it in the near future. Please pull, thanks. - only enable extent map shrinker for DEBUG builds, temporary quick fix to avoid latency spikes for regular builds - update target inode's ctime on unlink, mandated by POSIX - properly take lock to read/update block group's zoned variables - add counted_by() annotations ---------------------------------------------------------------- The following changes since commit 6252690f7e1b173b86a4c27dfc046b351ab423e7: btrfs: fix invalid mapping of extent xarray state (2024-08-13 15:36:57 +0200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux.git tags/for-6.11-rc3-tag for you to fetch changes up to 534f7eff9239c1b0af852fc33f5af2b62c00eddf: btrfs: only enable extent map shrinker for DEBUG builds (2024-08-16 21:22:39 +0200) ---------------------------------------------------------------- Jeff Layton (1): btrfs: update target inode's ctime on unlink Naohiro Aota (1): btrfs: zoned: properly take lock to read/update block group's zoned variables Qu Wenruo (2): btrfs: tree-checker: add dev extent item checks btrfs: only enable extent map shrinker for DEBUG builds Thorsten Blum (1): btrfs: send: annotate struct name_cache_entry with __counted_by() fs/btrfs/free-space-cache.c | 14 +++++---- fs/btrfs/inode.c | 1 + fs/btrfs/send.c | 2 +- fs/btrfs/super.c | 8 +++++- fs/btrfs/tree-checker.c | 69 +++++++++++++++++++++++++++++++++++++++++++++ 5 files changed, 86 insertions(+), 8 deletions(-) .
