Subject: [PATCH 06/13] vmcore: modify vmcore clean-up function to free buffer on 2nd kernel
Date: Thu, 14 Feb 2013 19:12:16 +0900 [thread overview]
Message-ID: <20130214101216.22466.52389.stgit@localhost6.localdomain6> (raw)
In-Reply-To: <20130214100945.22466.4172.stgit@localhost6.localdomain6>
Vmcore object has buffer on 2nd kernel if it has VMCORE_2ND_KERNEL
type, which needs to be freed.
