For the record, I'm not interested in this; I regularly re-order patches
and slapping them into CVS assumes a linear development cycle, prevents
patches being re-ordered, requires someone to maintain it, and requires
someone to pull the changes out and feed them upstream.

As long as there isn't an active large community, the last two listed
above suffers greatly - see handhelds.org and MTD CVS archives as an
excellent example: handhelds.org is a complete dead loss, full of crap
and MTD in Linus' tree is currently broken because no one is pushing
fixes upstream.

For some of us, we use scripts to patch and unpatch the kernel, so
the process of patch application/removal is dead simple.

rmk, currently running at 97 patches in 17 series maintained in this
manner with no problem.  See akpm's patch management system for another
example of this working well.
