[PATCH 0/5] misc filesystems: simplify sysctl registration

This simplifies syctl registration for a few misc filesystems according
to our latest preference / guidance [0]. register_sysctl_table() incurs
possible recursion and we can avoid that by dealing with flat
directories with files in them, and having the subdirectories explicitly
named with register_sysctl().

As we phase these callers out we can deprecate / remove register_sysctl_table()
eventually.

If you're a maintainer feel free to pick up the patch or I'm also happy
to take it through sysctl-next if you like. These don't create
conflicts so there is no requirement they go throug sysclt-next at all.

I can pick up stragglers later.
