Subject: [PATCH 4/4] selftests/cgroup: fix uninitialized variables in test_zswap.c
First of all, in order to build with clang at all, one must first apply
Valentin Obst's build fix for LLVM [1]. Once that is done, then when
building with clang, via:
make LLVM=1 -C tools/testing/selftests
..clang finds and warning about some uninitialized variables. Fix these
by initializing them.
