Subject: [PATCH 015/119] xfs: refactor btree owner change into a separate visit-blocks function
Date: Thu, 16 Jun 2016 18:19:28 -0700 [thread overview]
Message-ID: <146612636805.12839.15108503251791000478.stgit@birch.djwong.org> (raw)
In-Reply-To: <146612627129.12839.3827886950949809165.stgit@birch.djwong.org>
Refactor the btree_change_owner function into a more generic apparatus
which visits all blocks in a btree. We'll use this in a subsequent
patch for counting btree blocks for AG reservations.
