For fs, commit fc620fd made rootless field private, and for fs2, it was always private, and yet comments in both mention it as m.Rootless. Fix it. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
Commit 5d0ffbf added OOM kill count checking and better container start/run/exec error reporting in case we hit OOM. It also introduced warnings like these: > level=warning msg="unable to get oom kill count" error="openat2 > /sys/fs/cgroup/user.slice/user-1000.slice/user@1000.service/test_hello/memory.events: > no such file or directory" In case of rootless containers, unless cgroup is delegated or systemd is used, runc can not create a cgroup and thus it fails to get OOM kill count. This is expected, and the warning should not be shown in this case. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
