Qi Wang 72cfdce718 Allocate tcache stack from base allocator ... When using metadata_thp, allocate tcache bin stacks from base0, which means they will be placed on huge pages along with other metadata, instead of mixed with other regular allocations. In order to do so, modified the base allocator to support limited reuse: freed tcached stacks (from thread termination) will be returned to base0 and made available for reuse, but no merging will be attempted since they were bump allocated out of base blocks. These reused base extents are managed using separately allocated base edata_t -- they are cached in base->edata_avail when the extent is all allocated. One tricky part is, stats updating must be skipped for such reused extents (since they were accounted for already, and there is no purging for base). This requires tracking the "if is reused" state explicitly and bypass the stats updates when allocating from them.		2023-09-18 12:18:32 -07:00
