Jason Evans	a0dd3a4483	Implement per arena base allocators. ... Add/rename related mallctls: - Add stats.arenas.<i>.base . - Rename stats.arenas.<i>.metadata to stats.arenas.<i>.internal . - Add stats.arenas.<i>.resident . Modify the arenas.extend mallctl to take an optional (extent_hooks_t *) argument so that it is possible for all base allocations to be serviced by the specified extent hooks. This resolves #463.	2016-12-26 18:08:28 -08:00
Jason Evans	a6e86810d8	Refactor purging and splitting/merging. ... Split purging into lazy and forced variants. Use the forced variant for zeroing dss. Add support for NULL function pointers as an opt-out mechanism for the dalloc, commit, decommit, purge_lazy, purge_forced, split, and merge fields of extent_hooks_t. Add short-circuiting checks in large_ralloc_no_move_{shrink,expand}() so that no attempt is made if splitting/merging is not supported. This resolves #268.	2016-12-26 18:08:16 -08:00
Jason Evans	977103c897	Uniformly cast mallctl[bymib]() oldp/newp arguments to (void *). ... This avoids warnings in some cases, and is otherwise generally good hygiene.	2016-10-27 21:31:25 -07:00
Jason Evans	d51139c33c	Verify extent hook functions receive correct extent_hooks pointer.	2016-09-29 09:50:35 -07:00
Jason Evans	0c5cec833f	Relax extent hook tests to work with unsplittable extents.	2016-06-05 22:30:31 -07:00
Jason Evans	f8f0542194	Modify extent hook functions to take an (extent_t *) argument. ... This facilitates the application accessing its own extent allocator metadata during hook invocations. This resolves #259.	2016-06-05 21:00:02 -07:00
Jason Evans	22588dda6e	Rename most remaining *chunk* APIs to *extent*.	2016-06-05 20:42:23 -07:00
