From ba9e780246a15a35f8ebe5b60f4a11bb58e85bda Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 3 Aug 2016 11:26:33 +1000 Subject: xfs: add tracepoints and error injection for deferred extent freeing Add a couple of tracepoints for the deferred extent free operation and a site for injecting errors while finishing the operation. This makes it easier to debug deferred ops and test log redo. Signed-off-by: Darrick J.
