Hi Josh,
how can i log in AioRequest.h?
I need to add some debugging into:
void complete(int r)
{
if (should_complete(r)) {
if (m_hide_enoent && r == -ENOENT)
r = 0;
m_completion->complete(r);
delete this;
}
}
Move the implementation of the method out of the header and into
AioRequest.cc. Then you can use ldout like in the rest of that file.

Hello Josh,
after digging three days around i got it.
That's great!
The problem is in aio_discard in internal.cc. The i/o fails when AioZero
or AioTruncate is used.
Interesting, I wouldn't have expected the bug to be there. Is
it failing with a different error code, or just taking too long
so the guest kernel tries to cancel it?
It works fine with AioRemove. It seems to depend on overlapping.
Hopefully i'm able to provide a patch this nicht.
Looking forward to it!
Josh
