Subject: [PATCH v2 0/2] x86: add xen hypercall preemption
Date: Wed, 10 Dec 2014 15:34:45 -0800 [thread overview]
Message-ID: <1418254487-9988-1-git-send-email-mcgrof@do-not-panic.com> (raw)
From: "Luis R. Rodriguez" <mcgrof@suse.com>
This is my second series which addresses hypercall preemption
on Xen. On the first iteration of this series [0] I tried as
much as possible to avoid cond_resched() type of behaviour
but after good feedback I've determined using something like
cond_resched() but on IRQ context is required for preempting
Xen hypercalls. This introduces and uses the new cond_resched_irq().
