[PATCH] selinux: fix selinux_netlbl_inode_permission() locking
do not call a sleeping lock API in an RCU read section.
lock_sock_nested can sleep, its BH counterpart doesn't.
selinux_netlbl_inode_permission() needs to use the BH counterpart
unconditionally.
Compile tested.
From: Ingo Molnar <mingo@elte.hu>
added BH disabling, because this function can be called from non-atomic
contexts too, so a naked bh_lock_sock() would be deadlock-prone.
Boot-tested the resulting kernel.
