Subject: [PATCH 06/21] xfs: realtime rmap btree transaction reservations
Date: Tue, 31 Dec 2019 17:16:57 -0800 [thread overview]
Message-ID: <157784141746.1368137.11534756239035686215.stgit@magnolia> (raw)
In-Reply-To: <157784137939.1368137.1149711841610071256.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.
