would be nice to give better description, I do not really understand what are you looking for.

Welcome to LQ. Please take a few minutes to read my blog (about posting).

There are 'TONS' of kernel boot messages; most 'users' can ignore them.
You can read kernel source-code and/or Doc/..; it will cover the 'sub-sys'tem cpusets. Also: man [-k] {cgroups,cpuset}

Best wishes; enjoy your studying! p.s. Feel free to Intro your distro, PC, Linux experience/interests/goals.

Welcome to the forum.

Can you post an example from the log of the line in question? It'll will be easier to say something with a concrete example.

cgroups are control groups. I don't know what they do but systemd requires them, so all modern stock kernels are set to provide them.

Read the "Question Guidelines" link in my posting signature, and do basic research before posting. Putting your EXACT QUESTION into Google pulls up:
https://www.kernel.org/doc/Documenta...v1/cgroups.txt

...from the kernel.org website.

Read the LQ Rules and "Question Guidelines". You hijacked someone elses thread with your own question, re-opened a closed thread, and have provided no details at all that would let us even GUESS to begin to help you.

Open your own thread for your own question, and provide clear details.
