For lockres_free, if the lock is blocking by a lock request or
conversion request, then dlm_unlock just put it back to grant
queue, so need to ensure the lock is free finally.
I cannot think of a scenario where a DLM_CANCEL will be returned.
Could you explain the situation a bit more?
Thanks for the review. When the node is receiving message where it needs
to convert message
lock, and lockres_free is invoked if user stop array meanwhile, then the
message lock is put back
to grant queue at the CR mode and message lock is not released, am I
misunderstood the case?
In that case, this looks correct.
