From cf257abf02709dba3cc745d950f144ce49432b4f Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Mon, 20 May 2013 09:51:14 +1000 Subject: [PATCH] xfs: xfs_attr_shortform_allfit() does not handle attr3 format. xfstests generic/117 fails with: XFS: Assertion failed: leaf->hdr.info.magic == cpu_to_be16(XFS_ATTR_LEAF_MAGIC) indicating a function that does not handle the attr3 format correctly. Fix it.
