[ Upstream commit 00e38a5d753d7788852f81703db804a60a84c26e ]
The cgroup testing relys on the root cgroup's subtree_control setting,
If the 'memory' controller isn't set, some test cases will be failed
as following:
$sudo ./test_core
not ok 1 test_cgcore_internal_process_constraint
ok 2 test_cgcore_top_down_constraint_enable
not ok 3 test_cgcore_top_down_constraint_disable
...
To correct this unexpected failure, this patch write the 'memory' to
subtree_control of root to get a right result.

2.11.0
Hi,
I've tried to build kselftests for several years now, but I always
find the build broken. Which makes me wonder if the instructions are
broken or something. I follow the instructions in
Documentation/dev-tools/kselftest.rst and start with "make -C
tools/testing/selftests". Here is the errors I get on the upstream
commit 16d72dd4891fecc1e1bf7ca193bb7d5b9804c038:
error: unable to create target: 'No available targets are compatible
with triple "bpf"'

Here is full log:

I have libelf-dev installed. Do I need to install something else? Or
run some other command?
Thanks
