I agree; however I also think its unfair to pile this on Juri. Esp the avenue pushed here, which will increase UP text and (runtime) data sizes, to which I think some people will still object. There's this entire 'maker' community (aka. internet of things) now using very small Linux devices. Think Raspberry-Pi, Intel Quark (however much I hate Intel for shipping a new 32bit device) etc. These people are wanting to run Linux on these tiny devices, with tiny memories etc; we shouldn't make their life harder than it already is. Also; you didn't object about the 29 new #ifdefs currently in tip. How about we use some of the 'quality' conference time in EDI to do some big code shuffles to get rid of some of them. I'm sure we can reduce the number of ifdeffery by simply merging various similar blocks and maybe write a few extra helper functions. This is how kernel/sched/ got created in the first place; as a means to keep the fingers busy at a conference ;-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
