Xiantao,
This patch is pretty amazing, I can now get QEMU to start booting in a
few seconds with a 200GB setup, instead of the 20+ minutes it took
before.
I did see one time where I got what looked like a CPU deadlock, but I
have only seen it once, so it doesn't have to be because of this patch.
Well done!
Cheers,
Jes
