Subject: [PATCH 07/13] SUNRPC: Provide room in svc_rqst for larger addresses
Date: Mon, 13 Nov 2006 07:58:19 -0500	[thread overview]
Message-ID: <20061113125819.4435.84338.stgit@localhost.localdomain> (raw)
In-Reply-To: <20061113125640.4435.11957.stgit@localhost.localdomain>

Expand the rq_addr field to allow it to contain larger addresses.
