I'm struggling to find any documentation online relating to process number 54.

root        54  0.0  0.0      0     0 ?        S<   11:24   0:00 [kthrotld]
root     11385  0.0  0.0  12944   992 pts/0    S+   11:30   0:00 grep --color=auto kthrotld

I think it may be a kernel thread. Can anyone advise the purpose of this [kthrotld] and the documentation online where I can look this up?

Reading @muru's recommendation https://tiro.org.uk/posts/mystery-processes/

It's a kernel thread which:

is 'controlling IO bandwidth on a request queue' by throttling requests.
