Re: [PATCH v3 3/5] mm: convert compaction to zone lock wrappers

Compaction uses compact_lock_irqsave(), which currently operates
on a raw spinlock_t pointer so it can be used for both zone->lock
and lruvec->lru_lock. Since zone lock operations are now wrapped,
compact_lock_irqsave() can no longer directly operate on a
spinlock_t when the lock belongs to a zone.

Split the helper into compact_zone_lock_irqsave() and
compact_lruvec_lock_irqsave(), duplicating the small amount of
shared logic. As there are only two call sites and both statically
know the lock type, this avoids introducing additional abstraction
or runtime dispatch in the compaction path.

No functional change intended.
