SELinux: Condense super block security structure flags and cleanup necessary code.
The super block security structure currently has three fields for what are essentially flags. The flags field is used for mount options while two other char fields are used for initialization and proc flags. These latter two fields are essentially bit fields since the only used values are 0 and 1. These fields have been collapsed into the flags field and new bit masks have been added for them. The code is also fixed to work with these new flags. Signed-off-by: David P. Quigley <dpquigl@tycho.nsa.gov> Acked-by: Eric Paris <eparis@redhat.com> Signed-off-by: James Morris <jmorris@macbook.localdomain>
