Subject: [PATCH 04/13] btrfs: make should_end_transaction check time to run delayed refs
Date: Fri, 13 Mar 2020 17:23:21 -0400	[thread overview]
Message-ID: <20200313212330.149024-5-josef@toxicpanda.com> (raw)
In-Reply-To: <20200313212330.149024-1-josef@toxicpanda.com>

Currently snapshot deletion checks to see if it needs to throttle itself
before ending a transaction, however this only checks if there's enough
space for delayed refs, not how much time it'll take to run those
delayed refs.  Fix this by checking btrfs_should_throttle_delayed_refs
as well, which takes into account how much time it'll take to run
delayed refs.
