Subject: [PATCH 08/12] kexec: don't invoke OOM-killer for control page allocation
Date: Thu, 28 Apr 2016 10:28:24 +0100 [thread overview]
Message-ID: <E1aviFE-0000jS-UI@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20160428092644.GX19428@n2100.arm.linux.org.uk>
If we are unable to find a suitable page when allocating the control
page, do not invoke the OOM-killer: killing processes probably isn't
going to help.
