WebTraditional allocators manage memory in page-sized chunks. Transparent Huge Pages (THP) [4] provide an oppor-tunity for the kernel to opportunistically cover consecutive pages using hugepages in the page table. A memory allocator, superﬁcially, need only allocate hugepage-aligned and -sized memory blocks to take advantage of this support. WebIt scans through all the bins, sees all the holes and inefficiencies, and between getting and returning memory for the user, it tries to reshuffle the bins and keep an internal ledger of all the reshuffles it's made. Now there's many different algorithms and strategies for doing this shuffling, and a few different ways to generally do it.
