Linux 3.0?

Any chance of also cleaning up some parts of the public API that are sub-optimal, breaking user space compatibility?

Seems like that could be a good idea at some point.

In that case, 2.6 would need at least basic maintenance for at least 10 years.

Breaking userland API is bad.

How about changing the ELF magic number in some way to bring in a compatability layer ? OK: this does somewhat defeat the object, but all the depricated API could be kept in one module (hopefully rarely loaded).
This would allow old binaries to run.

I suspect that most programs would be OK on a recompile, only a few would genuinely break since they rely on really old/removed bits of the kernel API.

What do we do about bits of /proc that change ?

It would be nice if some kind of warning message could be generated in advance so that we would know what would break.
