Bin Liu 6b13adf375 Use SEC in PAC to reduce lock contention on the ecaches ... Add a small extent cache in front of the PAC ecaches. Allocs and dallocs that fit are served from per-shard SEC bins without taking the ecache mutex; overflow falls through to the backing ecaches, including ecache_pinned for pinned extents. The feature is gated behind experimental_pac_sec_nshards (default 0, disabled). To support independent HPA and PAC SEC instances, sec_alloc/sec_dalloc/sec_fill take an explicit shard argument, with HPA and PAC using separate TSD shard slots.		2026-05-28 10:16:09 -07:00
