Ocfs2 devel - Oct 2008 - [PATCH 1/1] ocfs2/xattr: Fix check of return value of ocfs2_start_trans().

Hi Joel,
	this should be in your xattr-28 branch I think.

On failure, ocfs2_start_trans() returns values like ERR_PTR(-ENOMEM),
so we should check whether handle is NULL. Fix them to use IS_ERR().
Jan has made the patch for other part in ocfs2(thank Jan for it), so
this is just the fix for fs/ocfs2/xattr.c.

	Agreed.  This is now in my xattr-28 branch.
