From: Darrick J. Wong <darrick.wong@xxxxxxxxxx> 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. Signed-off-by: Darrick J.
