Subject: Re: [PATCH] x86: kernel: cpu: resctrl: Fix kernel-doc in
 pseudo_lock.c

Hi Fabio,

Thank you very much for catching these. I am curious what your goal is 
because when I ran a kernel-doc check on the resctrl area there were 
many more warnings than are not addressed in this patch. Also, while 
this patch claims to fix the kernel-doc in pseudo_lock.c there seems to 
be a few more that are not addressed. Are you planning to submit more 
patches to do a cleanup of kernel-doc or are these the only ones 
bothering you for some reason?

Could you please fixup the subject to conform to this area:
"x86/resctrl: Fix kernel-doc in pseudo_lock.c"

For this subject to be accurate though it should fix all the kernel-doc 
warnings found in pseudo_lock.c - or if not it would be helpful to 
explain what the criteria for fixes are. I tested this by running:
$ scripts/kernel-doc -v -none arch/x86/kernel/cpu/resctrl/*

This is not correct. A more accurate description could be:
"select which measurement to perform on pseudo-locked region"
