[Qemu-devel] [PATCH] block: fix bdrv_ioctl called from coroutine

[Paolo Bonzini]

When called from a coroutine, bdrv_ioctl must be asynchronous just like
e.g. bdrv_flush.  The code was incorrectly making it synchronous, fix
it.

        Fam, any reason why you did it this way?  I don't see
        any coroutine caller, but it doesn't make much sense. :)
