Subject: [PATCH 0/2] Simplify RCU freeing of shadow pages
Date: Thu, 19 Apr 2012 19:26:35 +0300 [thread overview]
Message-ID: <1334852797-28167-1-git-send-email-avi@redhat.com> (raw)
This patchset simplifies the freeing by RCU of mmu pages.
Xiao, I'm sure you thought of always freeing by RCU. Why didn't you choose
this way? I saves a couple of atomics in the fast path.

KVM: MMU: Always free shadow pages using RCU
KVM: MMU: Recover space used by rcu_head in struct kvm_mmu_page
