[PATCH 03/11] sysctl: clarify register_sysctl_init() base directory order

From: Luis Chamberlain
Date: Thu Mar 02 2023 - 15:29:56 EST


Relatively new docs which I added which hinted the base directories needed
to be created before is wrong, remove that incorrect comment. This has been
hinted before by Eric twice already [0] [1], I had just not verified that
until now. Now that I've verified that updates the docs to relax the context
described.
