Move bg inactivity check out of purge inner loop.
...
I.e. do it once per call to arena_decay_stashed instead of once per muzzy purge.

74958567a4
PA: have expand take sizes instead of new usize.
...
This avoids involving usize, which makes some of the stats modifications more
intuitively correct.
2020-04-10 13:12:47 -07:00
David Goldblatt
5bcc2c2ab9
PA: Have expand take szind and slab.
...
This isn't really necessary, but having a uniform API will help us later.

This better facilitates testing.
2020-04-10 13:12:47 -07:00
David Goldblatt
bf55e58e63
Rename test/unit/decay -> test/unit/arena_decay.
...
This is really more of an end-to-end test at the arena level; it's not just of
the decay code in particular any more.
2020-04-10 13:12:47 -07:00

Arena stats: mark edata_avail as derived.
...
The true number is in the edata_cache itself.
2020-04-10 13:12:47 -07:00
David Goldblatt
3192d6b77d
Extents: Have extent_dalloc_gap take ehooks.
...
We're almost to the point where the extent code doesn't know about arenas at
all. In that world, we shouldn't pull them out of the arena.
2020-04-10 13:12:47 -07:00
David Goldblatt

...
Just another step towards making PA self-contained.
2020-04-10 13:12:47 -07:00
David Goldblatt

PA: Get rid of arena_ind_get calls.
...
This is another step on the path towards breaking the extent reliance on the
arena module.

PA: Move in decay stats.

Introduce lockedint module.
...
This pulls out the various abstractions where some stats counter is sometimes an
atomic, sometimes a plain variable, sometimes always protected by a lock,
sometimes protected by reads but not writes, etc. With this change, these cases
are treated consistently, and access patterns tagged.
In the process, we fix a few missed-update bugs (where one caller assumes
"protected-by-a-lock" semantics and another does not).

David Goldblatt

Move cache index randomization out of extent.
...
This is logically at a higher level of the stack; extent should just allocate
things at the page-level; it shouldn't care exactly why the callers wants a
given number of pages.
2020-04-10 13:12:47 -07:00
David Goldblatt
