From a6e8a8455c94565c53e1a1756d2ab9d9e3a902b8 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 20 Sep 2010 16:01:33 -0700 Subject: cifs: add function to get a tcon from cifs_sb When we convert cifs to do multiple sessions per mount, we'll need more than one tcon per superblock. At that point "cifs_sb->tcon" will make no sense. Add a new accessor function that gets a tcon given a cifs_sb. For now, it just returns cifs_sb->tcon. Later it'll do more.
