+Subject: xfs: fix up backport error in fs/xfs/xfs_inode.c
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+Commit c66edeaf79bb6f0ca688ffec9ca50a61b7569984, which was a backport of
+commit b1438f477934f5a4d5a44df26f3079a7575d5946 upstream, needed to have
+the error value be positive, not negative, in order to work properly.
