From 673930c34a4500c616cf9b2bbe1ae131ead2e155 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 3 Aug 2016 11:33:43 +1000 Subject: xfs: introduce rmap extent operation stubs Originally-From: Dave Chinner Add the stubs into the extent allocation and freeing paths that the rmap btree implementation will hook into. While doing this, add the trace points that will be used to track rmap btree extent manipulations.
