Subject: [patch 0/4] x86/irq: Plug a couple of cpu hotplug races
Date: Sun, 05 Jul 2015 17:12:28 -0000	[thread overview]
Message-ID: <20150705170530.849428850@linutronix.de> (raw)

Jin debugged a subtle race in the cpu hotplug code which caused my to
look deeper into this. So I unearthed quite a few racy constructs.

Aside of the x86 specific problems I discovered a generic issue which
needs to be addressed in the cpu hotplug code.

Thanks,

	tglx
