Ondrej Zajicek (work)	2fc8b4c4ba	Alloc: Use posix_memalign() instead of aligned_alloc() ... For compatibility with older systems use posix_memalign(). We can switch to aligned_alloc() when we commit to C11 for multithreading.	2022-02-08 22:42:00 +01:00
Maria Matejka	644e9ca94e	Directly mapped pages are kept for future use if temporarily not needed	2021-11-24 19:42:52 +00:00
Maria Matejka	886dd92eee	Slab: head now uses bitmask for used/free nodes info instead of lists ... From now, there are no auxiliary pointers stored in the free slab nodes. This led to strange debugging problems if use-after-free happened in slab-allocated structures, especially if the structure's first member is a next pointer. This also reduces the memory needed by 1 pointer per allocated object. OTOH, we now rely on pages being aligned to their size's multiple, which is quite common anyway.	2021-03-25 16:47:48 +01:00
