Hello Sven,
Quoted 3 lines · Sven Hoexter
cgroups-v1/v2 documentation got moved to the "admin-guide" subfolder and converted from .txt files to .rst
Thanks for your patch and for the ping, and sorry I did not respond earlier. I had not forgotten this patch, but I was still working out what to do with it.
The general philosophy in man-pages is to maintain historical information, since the man-pages that are installed on a system may not correspond to the kernel running on that system. In the context of your patch, what this means is that I would prefer to have text like:
[[
The kernel source file
.IR Documentation/admin\-guide/cgroup\-v2.rst
(or
.IR Documentation/admin-guide/cgroup-v2.rst in Linux x.y and earlier) ]]
Would you be willing to revise your patch to that style?
Thanks,
Michael

The general philosophy in man-pages is to maintain historical information, since the man-pages that are installed on a system may not correspond to the kernel running on that system.
Indeed, a valid point I did not consider.

Sure, I will prepare a new version.
