From b474c7ae4395ba684e85fde8f55c8cf44a39afaf Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Sun, 22 Jun 2014 15:04:54 +1000 Subject: xfs: Nuke XFS_ERROR macro XFS_ERROR was designed long ago to trap return values, but it's not runtime configurable, it's not consistently used, and we can do similar error trapping with ftrace scripts and triggers from userspace. Just nuke XFS_ERROR and associated bits.
