Subject: [PATCH 0/4] fixes for btrfs async discards
Date: Wed, 4 Nov 2020 09:45:50 +0000 [thread overview]
Message-ID: <cover.1604444952.git.asml.silence@gmail.com> (raw)
Several fixes for async discards. The first patch might increase discard
rate, drastically in some cases. That may be a suprise for those
assuming that hitting iops_limit is rare and rarther outliers. Though,
it still stays in allowed range, so should be fine.
Pavel Begunkov (4):
btrfs: discard: speed up discard up to iops_limit
btrfs: discard: save discard delay as ns not jiffy
btrfs: don't miss discards after override-schedule
btrfs: discard: reschedule work after param update
