Hello Stefan

    Hello Mitnick,

    asynchronous i/o is also missing in block/vpc.c.

    All newer block drivers support asynchronous reads and writes,
    only some old drivers don't.

    So adding asynchronous i/o to at least some of the old drivers
    would improve their usability.

    Look for "aio" in block/*.c to get a starting point.

I look for "aio" in block/*.c as a starting point of asynchronous i/o. And I

found that there isn't any "aio" keywords in block/vmdk.c. block/vmdk.c

is used as block driver for the VMDK format. Is it means that asynchronous

i/o is also missing in VMDK format?

thanks

Mitnick

Yes, it's also missing for VMDK.
