You rejected one of those prior to 1.2 that came from the STRIP driver
authors.
If it's the one that I'm thinking of, I can't blame Linus; they added
yet another kind of interrupt, which they called "adaptive", and the
code did things like (in the assembly stubs defined in irq.h), had some
hard-coded comparisons to see if the IP was the serial interrupt
handler, and other really, really unclean stuff.....
I took a look at one such patch, saw what they were trying to do, and
wrote a quick hack to the serial driver which at least solved the
problem for single-CPU systems (I was wondering if it would cause
problems for SMP systems, but I figured Linus would call me on it if it
did.)
So, I think Linus wants it done, but wants it done right. :-)
