Subject: [PATCH 0/2] nohz: Deal with clock reprogram skipping issues v3
Date: Fri, 19 May 2017 15:51:48 +0200	[thread overview]
Message-ID: <1495201910-12466-1-git-send-email-fweisbec@gmail.com> (raw)

v2 had issues on -tip tree and triggered a warning. It seems to have
disappeared. Perhaps it was due to another timer issue. Anyway this
version brings more debugging informations, with a layout that is more
bisection-friendly and it also handles ticks that fire outside IRQ
context and thus carry NULL irq regs. This happen when
hrtimer_interrupt() is called on hotplug cpu down for example.

We'll see if the issue arises again.

HEAD: cd15f46b284f04dbedd065a9d99a4e0badae379a

Thanks,
	Frederic
