Subject: [PATCH 0/4] btrfs: fix a couple swapfile support bugs
Date: Wed, 3 Feb 2021 11:17:43 +0000 [thread overview]
Message-ID: <cover.1612350698.git.fdmanana@suse.com> (raw)
From: Filipe Manana <fdmanana@suse.com>
The following patchset fixes 2 bugs with the swapfile support, where we can
end up falling back to COW when writing to an active swapfile. As a bonus,
it makes the NOCOW write patch, for both buffered and direct IO, more efficient
by avoiding doing repeated worked when checking if the target block group is
read-only.
Filipe Manana (4):
btrfs: avoid checking for RO block group twice during nocow writeback
btrfs: fix race between writes to swap files and scrub
btrfs: remove no longer used function btrfs_extent_readonly()
btrfs: fix race between swap file activation and snapshot creation
