Subject: [PATCH 3/8] kexec: don't invoke OOM-killer for control page allocation
Date: Fri, 03 Jun 2016 09:50:21 +0100 [thread overview]
Message-ID: <E1b8ko9-0004HG-R5@rmk-PC.armlinux.org.uk> (raw)
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.
