439219be7e Remove extent_can_coalesce arena dependency. 2019-12-20 10:18:40 -08:00

9cad5639ff Ehooks: remove arena_ind parameter.
This lives within the ehooks_t now, so that callers don't need to know it.

c792f3e4ab edata_cache: Remember the associated base_t.
This will save us some trouble down the line when we stop passing arena pointers
everywhere; we won't have to pass around a base_t pointer either.

ae23e5f426 Unify extent_alloc_wrapper with the other wrappers.
Previously, it was really more like extents_alloc (it looks in an ecache for an
extent to reuse as its primary allocation pathway).  Make that pathway more
explciitly like extents_alloc, and rename extent_alloc_wrapper_hard accordingly.

d8b0b66c6c Put extent_state_t into ecache as well as eset. 2019-12-20 10:18:40 -08:00

98eb40e563 Move delay_coalesce from the eset to the ecache. 2019-12-20 10:18:40 -08:00

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.

a7862df616 Rename extent_t to edata_t.
This frees us up from the unfortunate extent/extent2 naming collision.

a738a66b5c Ehooks: Add some debug zero and addr checks.
These help make sure that the ehooks return properly zeroed memory when required
to.

4b2e5ee8b9 Ehooks: Add a "zero" ehook.
This is the first API expansion.  It lets the hooks pick where and how to purge
within themselves.

403f2d1664 Extents: Split out introspection functionality.
This isn't really part of the core extent allocation facilities.  Especially as
this module grows, having it in its own place may come in handy.

92a511d385 Make extent module hermetic.
In the form of extent2.h.  The naming leaves something to be desired, but I'll
leave that for a later diff.
