Subject[patch 1/9] lockd: dont return EAGAIN from blocking lock request
From: Miklos Szeredi <mszeredi@suse.cz>

EAGAIN does not make sense as a return value from a blocking lock
request, the lock should be retried by the kernel until either it is
successful or fails permanently.

Looking at the server side NLM_LCK_DENIED means a permanent error in
this case, so just turn this into an ENOLCK.
