Subject: [PATCH 03/13] btrfs: make btrfs_should_throttle_delayed_refs only check run time
Date: Fri, 13 Mar 2020 17:23:20 -0400	[thread overview]
Message-ID: <20200313212330.149024-4-josef@toxicpanda.com> (raw)
In-Reply-To: <20200313212330.149024-1-josef@toxicpanda.com>

btrfs_should_throttle_delayed_refs checks run time of the delayed refs
and if there's enough space.  However we want to use these two checks
independently in the future, so make btrfs_should_throttle_delayed_refs
only check the runtime.  Then fix the only caller of
btrfs_should_throttle_delayed_refs to check the space as well, because
we want to throttle truncates on either space or time.
