From 04febabcf55beeffb8794a0d8c539e571bd2ae29 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Tue, 17 Jan 2012 16:09:15 -0500 Subject: cifs: sanitize username handling Currently, it's not very clear whether you're allowed to have a NULL vol->username or ses->user_name. Some places check for it and some don't. Make it clear that a NULL pointer is OK in these fields, and ensure that all the callers check for that.
