Changelog:
v8:
* Fixed a couple of build errors in the case of !CONFIG_MEMCG
* Simplified the online memcg selection scheme for the zswap global
limit reclaim (suggested by Michal Hocko and Johannes Weiner)
(patch 2 and patch 3)
* Added a new kconfig to allows users to enable zsw
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
for certain
This patch implements a helper function that try to get a reference to
an memcg's css, as well as checking if it is online. This new function
is almost exactly the same as the existing mem_cgroup_tryget(), except
for the onlineness check. In the !CONFIG_MEMCG case, it always returns
true, analogous
From: Domenico Cerasuolo
The memcg-zswap self test is updated to adjust to the behavior change
implemented by commit 87730b165089 ("zswap: make shrinking memcg-aware"),
where zswap performs writeback for specific memcg.

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
unlikely to be used again will reside in the pool, wasting precious
memory. It is hard to predict how much zswap space will be needed ahead
of time, as this
From: Domenico Cerasuolo
Currently, we only have a single global LRU for zswap. This makes it
impossible to perform worload-specific shrinking - an memcg cannot
determine which pages in the pool it owns, and often ends up writing
pages from other memcgs. This issue has been previously observed in
