Right, that'd definitely hide the problem for you. I'll see if I can get
it in a reproducible state and take it from there.
Though on the guest, if you could try with just this one applied:
http://git.kernel.dk/cgit/linux-block/commit/?h=wb-buf-throttle&id=f21fb0e42c7347bd639a17341dcd3f72c1a30d29
I'd appreciate it. It won't disable the throttling in the guest, just
treat META and PRIO a bit differently.
