Commit Message

Avri Altman April 16, 2024, 10:23 a.m. UTC 
Replace open-coded handling with cleanup.h guard(spinlock_irqsave) and
scoped_guard(spinlock_irqsave, ...).

There are some explicit spin_lock_irqsave/spin_unlock_irqrestore snaking
instances I left behind because I couldn't make heads or tails of it.
