From 50d971602a6c4bf1abe1f3873686f431d7539dfe Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Tue, 6 Jul 2010 20:43:01 -0400 Subject: cifs: set the port in sockaddr in a more clearly defined fashion This patch should replace the patch I sent a couple of weeks ago to set the port in cifs_convert_address. Currently we set this in cifs_find_tcp_session, but that's more of a side effect than anything. Add a new function called cifs_fill_sockaddr. Have it call cifs_convert_address and then set the port. This also allows us to skip passing in the port as a separate parm to cifs_find_tcp_session. Also, change cifs_convert_address take a struct sockaddr * rather than void * to make it clearer how this function should be called.
