Subject: [PATCH 20/20] btrfs: kill the priority_reclaim_space helper
Date: Wed, 29 Jan 2020 18:50:24 -0500	[thread overview]
Message-ID: <20200129235024.24774-21-josef@toxicpanda.com> (raw)
In-Reply-To: <20200129235024.24774-1-josef@toxicpanda.com>

Now that only the metadata stuff is using the helper, merge it into the
priority metadata reclaim loop.
