2024-05-19kernel: sched: Align 'tdq_lock' on cache line sizeIan Moffett
The lock should be aligned on a cache line boundary so it isn't in a cache line with other data. This is important for 'tdq_lock' as it is used by every processor which constantly acquires and releases it. This alignment can reduce how violently cache lines bounce between processor local caches.
