From: Chuck Lever Date: Tue, 5 Dec 2006 21:35:26 +0000 (-0500) Subject: SUNRPC: Move rpc_xprt socket connect fields into private data structure X-Git-Tag: v2.6.20-rc1~34^2~412^2~15 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c8475461829fd94f30208fbfa4eab7e5584c6495;p=linux-2.6 SUNRPC: Move rpc_xprt socket connect fields into private data structure Move the socket-specific connection management fields out of the generic rpc_xprt structure into a private data structure maintained in net/sunrpc/xprtsock.c.
