Cover letter [RFC patch 0/2] API renaming: "llist" (lockless list) to "llstack" (lockless stack)

Hi,

I am proposing these 2 patches:

1) Rename the llist API into llstack
2) make llstack_push return "prior empty state" information

The API change in (2) assumes that this "lockless list" behaves like a stack. Having a "list" API that has a stack behavior cast in stone does not make sense, but nevertheless some stack properties are really useful. So reflect the behavior of the lockless structure (stack/lifo) into the API.

These patches apply on Linux v3.1-rc4.

Comments are welcome,

Best regards,

Mathieu
