Smack: create a sysfs mount point for smackfs
There are a number of "conventions" for where to put LSM filesystems. Smack adheres to none of them. Create a mount point at /sys/fs/smackfs for mounting smackfs so that Smack can be conventional. Targeted for git://git.gitorious.org/smack-next/kernel.git Signed-off-by: Casey Schaufler <casey@schaufler-ca.com>
