Subject: [PATCH 02/13] btrfs: change btrfs_should_throttle_delayed_refs to a bool
Date: Fri, 13 Mar 2020 17:23:19 -0400 [thread overview]
Message-ID: <20200313212330.149024-3-josef@toxicpanda.com> (raw)
In-Reply-To: <20200313212330.149024-1-josef@toxicpanda.com>
We don't actually check the specific value from
btrfs_should_throttle_delayed_refs anywhere, just return a bool.
