Adding slab to partial list head/tail is sensentive to performance.
So adding a type to document it to avoid we get it wrong.

I think that if you want to make it more descriptive then using the stats
values (DEACTIVATE_TO_TAIL/HEAD) would avoid having to introduce an
additional enum and it would also avoid the if statement in the stat call.

ok, that's better.

Subject: slub: explicitly document position of inserting slab to partial list

Adding slab to partial list head/tail is sensitive to performance.
So explicitly uses DEACTIVATE_TO_TAIL/DEACTIVATE_TO_HEAD to document
it to avoid we get it wrong.

Frankly speaking, using DEACTIVATE_TO_TAIL/DEACTIVATE_TO_HEAD in
slab_alloc, slab_free make code hard to understand. Just adding some
comments will be more clear and understandable. like the following:
Do you think so?

Yes, I like that more.

fine, let me add it to the first patch
