Subject: [RFC PATCH v2 5/6] samples: livepatch: init reloc section array and mark as klp module
Date: Mon, 30 Nov 2015 23:21:18 -0500	[thread overview]
Message-ID: <1448943679-3412-6-git-send-email-jeyu@redhat.com> (raw)
In-Reply-To: <1448943679-3412-1-git-send-email-jeyu@redhat.com>

Create the array of klp relocation sections in the sample
klp_object (even if the array is empty in this case).

In addition, mark the module as a livepatch module so that
the module loader can appropriately identify and initialize it.
