Subject: [PATCH] anon_inode: set S_IFREG on the anon_inode

anon_inode_mkinode() sets inode->i_mode = S_IRUSR | S_IWUSR;  This means
that (inode->i_mode & S_IFMT) == 0.  This trips up some SELinux code that
needs to determine if a given inode is a regular file, a directory, etc.
The easiest solution is to just make sure that the anon_inode also sets
S_IFREG.
