Smack: fix smack_new_inode bogosities
In January of 2012 Al Viro pointed out three bits of code that he titled "new_inode_smack bogosities". This patch repairs these errors. 1. smack_sb_kern_mount() included a NULL check that is impossible. The check and NULL case are removed. 2. smack_kb_kern_mount() included pointless locking. The locking is removed. Since this is the only place that lock was used the lock is removed from the superblock_smack structure. 3. smk_fill_super() incorrectly and unnecessarily set the Smack label for the smackfs root inode. The assignment has been removed. Targeted for git://gitorious.org/smack-next/kernel.git Signed-off-by: Casey Schaufler <casey@schaufler-ca.com>
