Okay, I give up. 15 days, still no real progress. I don't see any point
in submitting any further patches for the kernel outside of those areas
that I maintain. Clearly no one cares enough to bother (a) properly
reviewing the patch, (b) applying the patch that Thomas thought
"makes tons of sense."
If patches that "makes tons of sense" just get ignored, then what does
the future of the kernel hold? Crap, that's what, utter crap.
As I said, it seems that the Linux kernel process is basically totally
broken and rotten. If a six line patch that "makes tons of sense" can't
be applied, then there's basically no hope what so ever.
FFS.
