| From | Vlastimil Babka <> | Subject | [RFC v2 27/34] mm, slub: don't disable irqs in slub_cpu_dead() | Date | Wed, 9 Jun 2021 13:38:56 +0200 |
| |
slub_cpu_dead() cleans up for an offlined cpu from another cpu and calls only functions that are now irq safe, so we don't need to disable irqs anymore.
