The patch titled Subject: cgroup: kselftest: relax fs_spec checks has been removed from the -mm tree. Its filename was cgroup-kselftest-relax-fs_spec-checks.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------ From: Chris Down chris@chrisdown.name Subject: cgroup: kselftest: relax fs_spec checks

On my laptop most memcg kselftests were being skipped because it claimed cgroup v2 hierarchy wasn't mounted, but this isn't correct. Instead, it seems current systemd HEAD mounts it with the name "cgroup2" instead of "cgroup":

% grep cgroup /proc/mounts cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate 0 0

I can't think of a reason to need to check fs_spec explicitly since it's arbitrary, so we can just rely on fs_vfstype.

After these changes, `make TARGETS=cgroup kselftest` actually runs the cgroup v2 tests in more cases.
