Re: [PATCH 2/8] bpf: new GCC port
I didn't expect this to be contested and not by a frequent
reviewer, but since you took the time to express yourself, I'll
do the same.

I don't know about that. But, if that's a valid observation
then I'd say people just tend to generally drift to the path of
least resistance for the immediate task at hand. It's rarely an
indication of *good* practice by itself, but perhaps that it's
time to bring it up.

You mean the autoconf version, I guess. That's about the only
value of including generated files; for newcomers that miss
using matched versions. Including bulk in patches can also
cause grief by messages being lost when they exceed the

IMHO sanity for gcc-patches is maximum review-value and
readability for others, avoiding redundancy. I'd just think
sending generated files for review is as redundant now as it was
when that advice was added.
Though, if you as a frequent reviewer believe that the valued
majority of reviewers and readers thinks differently, I suggest
taking steps to update the advice. Either way, keep the advice
up-to-date, for sanity.
