From c543838a1e00a5f8791e59ae570b1030d70906f2 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 3 Aug 2016 11:42:39 +1000 Subject: xfs: teach rmapbt to support interval queries Now that the generic btree code supports querying all records within a range of keys, use that functionality to allow us to ask for all the extents mapped to a range of physical blocks.
