Subject: [PATCH] xen/pciback: use resource_size()
Date: Sat, 06 Aug 2011 11:05:35 +0200 [thread overview]
Message-ID: <1312621538.5589.45.camel@localhost.localdomain> (raw)
From: Thomas Meyer <thomas@m3y3r.de>
Use resource_size function on resource object
instead of explicit computation.
The semantic patch that makes this output is available
in scripts/coccinelle/api/resource_size.cocci.
More information about semantic patching is available at
