Hi All,

Amongst all these RPC which all are for lock related request and which do
not ask for locks .E.g OBD_PING does not asks for locks where as
LDLM_ENQUEUE is the main entry point for handling lock related request.It
would also be great if you can tell me with which system call which RPC
might be invoked.Thanks.
