NetLabel: SELinux cleanups
This patch does a lot of cleanup in the SELinux NetLabel support code. A summary of the changes include: * Use RCU locking for the NetLabel state variable in the skk_security_struct instead of using the inode_security_struct mutex. * Remove unnecessary parameters in selinux_netlbl_socket_post_create(). * Rename selinux_netlbl_sk_clone_security() to selinux_netlbl_sk_security_clone() to better fit the other NetLabel sk_security functions. * Improvements to selinux_netlbl_inode_permission() to help reduce the cost of the common case.
