-Subject: btrfs: add KCSAN annotations for unlocked access to block_rsv->full
-
-From: David Sterba <dsterba@suse.com>
-
-[ Upstream commit 748f553c3c4c4f175c6c834358632aff802d72cf ]
-
-KCSAN reports that there's unlocked access mixed with locked access,
-which is technically correct but is not a bug. To avoid false alerts at
-least from KCSAN, add annotation and use a wrapper whenever ->full is
-accessed for read outside of lock.
-
-It is used as a fast check and only advisory. In the worst case the
-block reserve is found !full and becomes full in the meantime, but
-properly handled.
-
-Depending on the value of ->full, btrfs_block_rsv_release decides
-where to return the reservation, and block_rsv_release_bytes handles a
-NULL pointer for block_rsv and if it's not NULL then it double checks
-the full status under a lock.
