Hi,

ublk can passthrough I/O requests to userspce daemons. It is very important
to test ublk crash handling since the userspace part is not reliable.
Especially we should test removing device, killing ublk daemons and user
recovery feature.

The first patch add user recovery support in miniublk.

The second patch add five new tests for ublk to cover above cases.

V3:
- run "make check" to avoid warnings
- cleanup code
- just choose ext4 to make ublk/003 more reliable

V2:
- Check parameters in recovery
- Add one small delay before deleting device
- Write informative description
