[PATCH 3/7] KVM: MMU: Make kvm_mmu_slot_remove_write_access() rmap based

2013-01-08 Thread Takuya Yoshikawa
This makes it possible to release mmu_lock and reschedule conditionally in a later patch. Although this may increase the time needed to protect the whole slot when we start dirty logging, the kernel should not allow the userspace to trigger something that will hold a spinlock for such a long time
