That's because the "big QEMU lock" is held by the thread that called
qemu_aio_cancel.
and i also see
no cancellation message in kernel log.
And that's because the UNMAP actually ultimately succeeds. You'll
probably see soft lockup messages though.
The solution here is to bump the timeout of the UNMAP command (either in
the kernel or in libiscsi, I didn't really understand who's at fault).
What's your suggestion / idea about that?
