[Qemu-devel] [PATCH 0/3] trace: Fix event tracing during vCPU hot-unplug

[Lluís Vilanova]

The vCPU list needs to be locked to avoid memory corruption with concurrent
hot-(un)plugs, and per-vCPU events need to be disabled during vCPU hot-unplug.

Also adds event "guest_cpu_exit" to track vCPU hot-unplugging.
