Changelog:
v3:
	* More cleanup (patch 3) (suggested by Yosry Ahmed).
	* Check swap peak in swapin test
v2:
	* Make the swapin test also checks for zswap usage (patch 3)
	  (suggested by Yosry Ahmed)
	* Some test simplifications/cleanups (patch 3)
	  (suggested by Yosry Ahmed).

Fix a broken zswap kselftest due to cgroup zswap writeback counter
renaming, and add 2 zswap kselftests, one to cover the (z)swapin case,
and another to check that no zswapping happens when the cgroup limit is
0.

Also, add the zswap kselftest file to zswap maintainer entry so that
get_maintainers script can find zswap maintainers.

Nhat Pham (3):
  selftests: zswap: add zswap selftest file to zswap maintainer entry
  selftests: fix the zswap invasive shrink test
  selftests: add zswapin and no zswap tests
