[sheepdog] [PATCH v2 0/7] revive VDI locking mecahnism

[Valerio Pachera]

I've been testing also kill and kill -9.
With kill the lock gets removed.
With kill -9 it doens't (as expected).

'vdi lock force-unlock' works fine but I notices 2 things:

1) the syntax doesn't mentions 'vdiname'
dog vdi lock {list|force-unlock} [-a address] [-p port] [-h] [-t]
it should be
dog vdi lock {list|force-unlock} [-a address] [-p port] [-h] [-t] <vdiname>

2) if I don't write any vdi name, it crashes:

dog vdi lock force-unlock
dog exits unexpectedly (Segmentation fault).
