Subject: [PATCH v5 07/11] xfs: refactor allocation tree fixup code
Date: Fri, 27 Sep 2019 13:17:58 -0400 [thread overview]
Message-ID: <20190927171802.45582-8-bfoster@redhat.com> (raw)
In-Reply-To: <20190927171802.45582-1-bfoster@redhat.com>
Both algorithms duplicate the same btree allocation code. Eliminate
the duplication and reuse the fallback algorithm codepath.
