Re: [Qemu-devel] [patch] non-blocking disk IO

[Fabrice Bellard]

Thank you for the patch. I'll look at it ASAP. If there is no regression 
(in terms of bugs and performance) I will include it soon: I consider 
that non blocking I/O is now a critical feature in QEMU in order to get 
better performances.

Fabrice.
