[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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@xxxxxxxxxxxxxx>
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.
