Currently, we only have a single global LRU for zswap. This makes it

Since zswap now writes back pages from memcg-specific LRUs, we now need a

The interface of list_lru is based on the assumption that the list node
and the data it represents belong to the same allocated on the correct
node/memcg. While this assumption is valid for existing slab objects LRU
such as dentries and inodes, it is undocumented, and rather inflexible

Currently, we only shrink the zswap pool when the user-defined limit is
hit. This means that if we set the limit too high, cold data that are

The original patch missed a list_lru_del() -> list_lru_del_obj()
conversion. This patch fixed that.
