From a50fea26b9d2aa7b66fdd6d9579de10827ec086a Mon Sep 17 00:00:00 2001 From: Tom Tucker Date: Sun, 30 Dec 2007 21:07:59 -0600 Subject: svc: Make svc_send transport neutral Move the sk_mutex field to the transport independent svc_xprt structure. Now all the fields that svc_send touches are transport neutral. Change the svc_send function to use the transport independent svc_xprt directly instead of the transport dependent svc_sock structure.
