Subject: [RFC PATCH v3 09/10] fadump: Invalidate the fadump registration during machine shutdown.
Date: Mon, 31 Oct 2011 22:42:55 +0530 [thread overview]
Message-ID: <20111031171255.12259.80160.stgit@mars.in.ibm.com> (raw)
In-Reply-To: <20111031170200.12259.27663.stgit@mars.in.ibm.com>
From: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com>
If dump is active during system reboot, shutdown or halt then invalidate
the fadump registration as it does not get invalidated automatically.
