Subject: [PATCH 0/6] btrfs: fix some data races during fsync and cleanups
Date: Wed,  4 Oct 2023 11:38:47 +0100	[thread overview]
Message-ID: <cover.1696415673.git.fdmanana@suse.com> (raw)

From: Filipe Manana <fdmanana@suse.com>

The following remove some data races affecting mostly fsync. In general
these are mostly harmless from a functional perspective, though there are
a few cases that could cause some unexpected results but should be very
rare to hit. There's also a couple cleanups here.
More details on the changelogs.

Filipe Manana (6):
  btrfs: add and use helpers for reading and writing last_log_commit
  btrfs: add and use helpers for reading and writing log_transid
  btrfs: add and use helpers for reading and writing fs_info->generation
  btrfs: add and use helpers for reading and writing last_trans_committed
  btrfs: remove pointless barrier from btrfs_sync_file()
  btrfs: update comment for struct btrfs_inode::lock
