Subject: [GIT pull] timer fix for 4.15
Date: Wed, 17 Jan 2018 16:32:38 +0100 (CET)	[thread overview]
Message-ID: <alpine.DEB.2.20.1801171621530.1777@nanos> (raw)

Linus,

please pull the latest timers-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-urgent-for-linus

A one-liner fix which prevents deferrable timers becoming stale when the
system does not switch into NOHZ mode.

Thanks,

	tglx
