/proc/<pid>/stat utime not updating

I was trying to get cpulimit by opsengine to work on iSH. Walking through its source code, I found it depends on getting the utime (user mode jiffies) of a process in the /proc/\/stat pseudo-file. However, this parameter is always zero, and never changes. There may also
be other parameters that don't change, but I have not investigated them yet.

More information can be found in this file:
[extraInfo.txt](https://github.com/ish-app/ish/files/5934767/extraInfo.txt)

Reproduce the issue using the /proc//stat pseudo-file and compare its utime value while a process runs. Review extraInfo.txt and the behavior expected by cpulimit by opsengine. Done means utime updates for running processes, with any additional unchanged parameters identified and addressed if confirmed.
