Merge branch 'test_rhashtable-dont-allocate-huge-static-array'

Florian Westphal says:

====================
test_rhashtable: don't allocate huge static array

Add a test case for the rhlist interface.
While at it, cleanup current rhashtable test a bit and add a check
for max_size support.

No changes since v1, except in last patch.
kbuild robot complained about large onstack allocation caused by
struct rhltable when lockdep is enabled.
