Subject: [PATCH] xfsrestore: fix multi stream support
Date: Tue, 1 Oct 2013 11:30:38 -0500	[thread overview]
Message-ID: <524AF8AE.5030300@sgi.com> (raw)

If no extents exist, there is no need to call partial_reg() because
there is no data to split up. Also remove the uneeded check in 
partial_reg() to detect if this is a multistream restore.

Signed-off-by: Rich Johnston <rjohnston@sgi.com>
