The lockdep_assert_irqs_disabled() was a BUG_ON() statement in the beginning and it was added just before the "spin_lock(siglock)" statement to ensure this lock was taken with disabled interrupts. This is no longer the case: the siglock is acquired via lock_task_sighand() and this function already disables the interrupts. The lock is also acquired before this "lockdep_assert_irqs_disabled" so it is beset to remove it.
