The errortag knob has replaced the previous custom knob in the kernel. Create a local helper to support the old knob for backwards compatibility. Signed-off-by: Brian Foster --- This updates xfs/141 to use the new error injection tag sysfs knob that has replaced log_badcrc_factor in the latest XFS for-next tree.
