We've told you that we don't care what format your internal whatever uses
for these macros.

We have standards, tastes, and desires and reasons for naming macros
in a certain way in upstream kernel code.

I consider it flat out unacceptable to use macros with one letter
prefixes like "S_".  You simply should not do this.

Why?

Because you are polluting the global name space, that's why.

You should only define macros with very-likely-to-be-unique prefixes
otherwise you and some arch/* header file are going to define the same
thing.

This is not just theory, it has happened in the past.

I'm not applying this series, fixup your macros properly.  And to
repeat, complaints about how your internal tools generate things
will fall on deaf ears.

Thanks.
