Subject: [PATCHSET 0/2] sync discard
Date: Mon, 30 Apr 2018 09:32:50 -0600 [thread overview]
Message-ID: <1525102372-8430-1-git-send-email-axboe@kernel.dk> (raw)
We recently had a pretty severe perf regression with the XFS async
discard. This small series add a SYNC issue discard flag, and also
limits the chain size for sync discards. Patch 2 adds support for
reverting XFS back to doign sync discards.
