Subject: [PATCH 07/29] xfs: realtime rmap btree transaction reservations
Date: Thu, 25 Aug 2016 16:59:20 -0700	[thread overview]
Message-ID: <147216956023.7022.15229255210665379699.stgit@birch.djwong.org> (raw)
In-Reply-To: <147216950911.7022.438115723996286926.stgit@birch.djwong.org>

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.
