Hi Jens,

The 1st patch adds generic_01.sh for checking if IO is dispatched in order.

The 2nd ~ 7th patches clean up and simplify target implementation, add zc
for for null, which is useful for evaluating/comparing perf.

The 8th patch adds ublk/stripe target and two tests, which will be useful
for verifying multiple IOs aiming at same fixed kernel buffer, also can
be used for verifying vectored fixed kernel buffer in future if this
feature can be supported.
