[lvm-devel] [RFC 5/6] Add another policy for the missing device -- wait

[Lidong Zhong]

We add another policy for the missing device. If the missing deivce
could not come back with in the waiting time, then it will excute the
original policy(remove/allocate)
Not sure about the vsn() meaning, so I put down the kernel version...
