Yeah. I see that. You have a switch for the KSFT_ values. Since there is no
dependency on the cgroup tree, I would recommend having this patch go through
kselftest tree which is the normal process for tests anyway.

This version is good and I can apply this to linux-kselftest next. I ran a
quick test and the Skip case looks good.

TAP version 13
selftests: cgroup: test_memcontrol
========================================
1..0 # Skipped: memory controller isn't available
not ok 1..1 selftests: cgroup: test_memcontrol [SKIP]


Tejun! Please send me your Ack.

thanks,
-- Shuah
