Subject: [PATCH 06/19] xfs: realtime rmap btree transaction reservations
Date: Thu, 31 Aug 2017 13:34:01 -0700	[thread overview]
Message-ID: <150421164172.17458.15650269091757507699.stgit@magnolia> (raw)
In-Reply-To: <150421160433.17458.10817316901867396010.stgit@magnolia>

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

Make sure that there's enough log reservation to handle mapping
and unmapping realtime extents.  We have to reserve enough space
to handle a split in the rtrmapbt to add the record and a second
split in the regular rmapbt to record the rtrmapbt split.
