Subject: [PATCH 02/12] KVM: Documentation: Fix reentry-to-be-consistent paragraph
Date: Tue, 30 Oct 2012 11:02:15 +0100	[thread overview]
Message-ID: <1351591345-23071-3-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1351591345-23071-1-git-send-email-agraf@suse.de>

All user space offloaded instruction emulation needs to reenter kvm
to produce consistent state again. Fix the section in the documentation
to mention all of them.
