Subject: [PATCH 1/3] kexec: don't invoke OOM-killer for control page allocation
Date: Thu, 14 Apr 2016 21:00:02 +0100 [thread overview]
Message-ID: <E1aqnQo-0001Tu-Ch@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20160414195938.GV19428@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.
