There is, unfortunately, a long history where the appropriate kernel
developers have had no knowledge of bugs that have been introduced
by changes that have been made, simply because users report them on
things like web forums or other mailing lists.

In the normal process of things, the bugs have only found out about
years later, maybe when someone finally contacts the appropriate
kernel developers pointing out the problem.

A case in point was the removal of bogomips from /proc/cpuinfo, which
resulted in kernel developers being roasted by Linus when it was
pointed out that users had been reporting the problem on forums for
over a year. Apparently, it was _our_ fault for not knowing about
them.

Similar seems to be happening with my SFP work - it seems people would
much rather report problems on random forums around the Internet rather
than send an email to anyone who can fix the problem in mainline
kernels.

Kernel development is fundamentally a difficult, frustrating and
depressing activity.
