Subject: [PATCH 07/20] xfs: realtime rmap btree transaction reservations
Date: Thu, 25 Aug 2016 16:44:11 -0700	[thread overview]
Message-ID: <147216865128.3688.1537361834919049399.stgit@birch.djwong.org> (raw)
In-Reply-To: <147216860614.3688.3200692982609112535.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.
