Subject: [PATCH] kexec: do not call kmsg_dump in crashdump
Date: Fri, 25 Nov 2011 16:19:59 +0800 [thread overview]
Message-ID: <20111125081959.GA2505@darkstar.nay.redhat.com> (raw)
mtd/ram oops dumper will make more functions envolved. In case crash kexec,
we should avoid kmsg dumper to ensure crashdump success.
kill kmsg_dump callback while crash dumping
