Subject: [PATCH LIVEPATCH-BUILD-TOOLS 1/2] Ignore .discard sections
Date: Fri, 9 Jun 2017 17:03:35 +0100 [thread overview]
Message-ID: <20170609160336.13351-1-ross.lagerwall@citrix.com> (raw)
Ignore differences in discard sections. They are not included in the final xen
binary so there is no need to include them in the live patch.
