  "message": "signal: Explain local_irq_save() call\n\nThe explicit local_irq_save() in __lock_task_sighand() is needed to avoid\na potential deadlock condition, as noted in a841796f11c90d53 (signal:\nalign __lock_task_sighand() irq disabling and RCU).  However, someone\nreading the code might be forgiven for concluding that this separate\nlocal_irq_save() was completely unnecessary.  This commit therefore adds\na comment referencing the shiny new block comment on rcu_read_unlock().\n\nReported-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nSigned-off-by: Paul E.
