net: Remove BKL from tun The lock_kernel/unlock_kernel() in cycle_kernel_lock() which is called in tun_chr_open() is not serializing against anything and safe to remove. tun_chr_fasync() is serialized by get/put_tun() and fasync_helper() has no dependency on BKL. The modification of tun->flags is racy with and without the BKL so removing it does not make it worse. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: David S.
