It will disable CONFIG_DEBUG_FS.  That's OK if that's what you want to do.

But this will just give you something to begin with. It will need more work.
There are lots of config options that use "select" to force another config
option to be set/enabled. Even if you disable an option and you have one of
these other options set/enabled, they will just enable the DEBUG/TRACE options
again for you.

When you find one of these, they pretty much have to be checked and tuned
one-by-one. It can take a lot of time to do that.
