Date: Thu, 26 Mar 2015 10:08:54 +0000 [thread overview]
Message-ID: <1427364534-136269-1-git-send-email-long.wanglong@huawei.com> (raw)
This patch update the module parameter backend, so it is visible
through /sys/module/pstore/parameters/backend.

ramoops
and without this patch:
# cat /sys/module/pstore/parameters/backend
(null)
