Subject: [ 02/44] SUNRPC: return negative value in case rpcbind client creation error

From: Greg KH <gregkh@...uxfoundation.org>

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stanislav Kinsbursky <skinsbursky@...allels.com>

commit caea33da898e4e14f0ba58173e3b7689981d2c0b upstream.

Without this patch kernel will panic on LockD start, because lockd_up() checks
lockd_up_net() result for negative value.
>>From my pow it's better to return negative value from rpcbind routines instead
of replacing all such checks like in lockd_up().
