Subject: [PATCH 16/39] xfs: support scrubbing refcount btree
Date: Fri, 04 Nov 2016 17:26:18 -0700	[thread overview]
Message-ID: <147830557798.4165.9601630741560607905.stgit@birch.djwong.org> (raw)
In-Reply-To: <147830546754.4165.17790362300876898017.stgit@birch.djwong.org>

Plumb in the pieces necessary to check the refcount btree.  If rmap is
available, check the reference count by performing an interval query
against the rmapbt.

v2: Handle the case where the rmap records are not all at least the
length of the refcount extent.
