I wrote "multithreaded" but I really meant "multicore". If two cores are contending for a lock I don't see how irq protection help. As long as there is only one core, I agree.

On most multicore systems you can pin the IRQ handling to a single core. Pinning locking interrupts to a single core would be how you handle this.

True, but locks are not only needed inside IRQ handler routines.
