Bug Description
I installed Ubuntu 22.04 and then followed instructions at: https:/
to install the realtime patch (ua enable realtime-kernel --beta) and rebooted the server. Subsequently when I installed kubernetes, I noticed that most of system pods were not coming up. The error was as shown below:
Warning Failed 33m kubelet Error: container create failed: time="2022-
I then noticed that "memory" was missing from "/sys/fs/
root@cran-ubuntu:~# cat /sys/fs/
cpuset cpu io hugetlb pids rdma misc
I then re-installed the Ubuntu 22.04 (I.e., without rt patch) and I could see that "memory" is present in "/sys/fs/
root@cran-ubuntu:~# cat /sys/fs/
cpuset cpu io memory hugetlb pids rdma misc
Also, "memory.events" file can be found under sub-directories in the /sys/fs/cgroup/ Path
To summarize, when the rt patch is installed, "memory" is being removed from "/sys/fs/

Thanks for the bug report, Srinivas.
I am going to setup an environment to try and reproduce this issue. I should have an update for you shortly.
