Subject: [PATCH 0/2] mild btrfs async discard fix
Date: Mon, 30 Nov 2020 16:22:15 +0000 [thread overview]
Message-ID: <cover.1606752605.git.asml.silence@gmail.com> (raw)
The first fixes torn reads, that is not very important but costs us
nothing. The second optimises out extra spinlocking that may be useful
for high discard rates.
Pavel Begunkov (2):
btrfs: fix racy access to discard_ctl data
btrfs: don't overabuse discard lock
