Qi Wang	deb8e62a83	Implement guard pages. ... Adding guarded extents, which are regular extents surrounded by guard pages (mprotected). To reduce syscalls, small guarded extents are cached as a separate eset in ecache, and decay through the dirty / muzzy / retained pipeline as usual.	2021-09-26 16:30:15 -07:00
David Goldblatt	4ca3d91e96	Rename geom_grow -> exp_grow. ... This was promised in the review of the introduction of geom_grow, but would have been painful to do there because of the series that introduced it. Now that those are comitted, renaming is easier.	2020-11-13 13:42:33 -08:00

David Goldblatt	131b1b5338	Rename ecache_grow -> geom_grow. ... We're about to start using it outside of the ecaches, in the HPA central allocator.	2020-08-19 16:53:21 -07:00

David Goldblatt	bb70df8e5b	Extent refactor: Introduce ecache module. ... This will eventually completely wrap the eset, and handle concurrency, allocation, and deallocation. For now, we only pull out the mutex from the eset.	2019-12-20 10:18:40 -08:00
