Subject: [PATCH 06/20] xfs: halt auto-reclamation activities while rebuilding rmap
Date: Thu, 22 Feb 2018 18:02:21 -0800	[thread overview]
Message-ID: <151935134185.22097.12332431438284992923.stgit@magnolia> (raw)
In-Reply-To: <151935130484.22097.9694510081310029779.stgit@magnolia>

From: Darrick J. Wong <darrick.wong@oracle.com>

Rebuilding the reverse-mapping tree requires us to quiesce all inodes in
the filesystem, so we must stop background reclamation of post-EOF and
CoW prealloc blocks.
