[Qemu-devel] [PATCH 0/8] Make icount thread-safe

2013-10-08 Thread Paolo Bonzini
This series moves the icount state under the same seqlock as the "normal" vm_clock implementation. It is not yet 100% thread-safe, because the CPU list should be moved under RCU protection (due to the call to !all_cpu_threads_idle() in qemu_clock_warp). However it is a substantial step forward, t
