[00/13] sysctl: spring cleaning

Message

Luis Chamberlain May 29, 2020, 7:40 a.m. UTC

Me and Xiaoming are working on some kernel/sysctl.c spring cleaning.
During a recent linux-next merge conflict it became clear that
the kitchen sink on kernel/sysctl.c creates too many conflicts,
and so we need to do away with stuffing everyone's knobs on this
one file.

This is part of that work. This is not expected to get merged yet, but
since our delta is pretty considerable at this point, we need to piece
meal this and collect reviews for what we have so far. This follows up
on some of his recent work.

This series focuses on a new helper to deal with subdirectories and
empty subdirectories. The terminology that we will embrace will be
that things like "fs", "kernel", "debug" are based directories, and
directories underneath this are subdirectories.

In this case, the cleanup ends up also trimming the amount of
code we have for sysctls.

If this seems reasonable we'll kdocify this a bit too.

This code has been boot tested without issues, and I'm letting 0day do
its thing to test against many kconfig builds. If you however spot
any issues please let us know.
