From 8f690d2497b6acda01c7efa23644fe7fc4ee937a Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Mon, 9 Jan 2017 20:18:49 -0600 Subject: [PATCH] xfs: handle cow fork in xfs_bmap_trace_exlist Source kernel commit: c44a1f22626c153976289e1cd67bdcdfefc16e1f By inspection, xfs_bmap_trace_exlist isn't handling cow forks, and will trace the data fork instead. Fix this by setting state appropriately if whichfork == XFS_COW_FORK.
