From 1028b1a6b0e0547e101ec543e73901aecf4d1a34 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Sun, 26 May 2013 07:01:00 -0400 Subject: [PATCH] cifs: add new fields to cifs_ses to track requested security flavor Currently we have the overrideSecFlg field, but it's quite cumbersome to work with. Add some new fields that will eventually supercede it.
