[PATCH] NFSv4: setlease should return EAGAIN if locks are not available

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

Instead of returning ENOLCK when we can't hand out a lease, we should be
returning EAGAIN.
