Subject: [PATCH 0/2] make kvm guest mode to be rcu quiescent state
Date: Thu, 28 Apr 2011 12:52:01 +0300 [thread overview]
Message-ID: <1303984323-3203-1-git-send-email-gleb@redhat.com> (raw)
CPU may spend a lot of time in a guest mode while other CPUs wait for
rcu grace period to elapse. This patch series makes guest mode into
quiescent state to shorten wait time.
Gleb Natapov (2):
rcu: export rcu_note_context_switch() function
KVM: make guest mode entry to be rcu quiescent state
