We have a bunch of headers without multiple inclusion guards. Some are
clearly intentional, some look accidental. Too many for me to find out
by examining each of them, so I'm asking their maintainers.
Why do I ask? I'd like to mark the intentional ones and fix the
accidental ones, so they don't flunk "make check-headers" from "[RFC v4
0/7] Baby steps towards saner headers" just because they lack multiple
inclusion guards.
Just in case: what's a multiple inclusion guard? It's
#ifndef UNIQUE_GUARD_SYMBOL_H
#define UNIQUE_GUARD_SYMBOL_H
...
#endif
with nothing but comments outside the conditional, so that the header
can safely be included more than once.
I append the alphabetical list of headers without multiple inclusion
guards (as reported by scripts/clean-header-guards -nv), followed by the
same list sorted into maintainer buckets. If you're cc'ed, please find
your bucket(s), and tell me which headers intentionally lack guards.
