wait_event_interruptible_locked_irq was introduced by commit 22c43c81a51e
("wait_event_interruptible_locked() interface"), but older code such as
eventfd_{write,read} still uses the open code implementation.
Inspired by commit 8120a8aadb20
("fs/timerfd.c: make use of wait_event_interruptible_locked_irq()"), this
patch replaces the open code implementation with a single macro call.
No functional change intended.
Looks pretty reasonable to me. How did you test it?
Thanks.
We have verified it in some local testing environments, and the
intel-lab-lkp has also tested it more than a month, as follows:
