Perhaps after 2.6.n is out and stable for a month or so someone could look at the problem. Certainly the various io schedulers are good candidates for being optional and/or modules. The problem is that the parts which aren't needed aren't large, so you may not gain much.
Clearly you have to have *some* io scheduler, I'm not sure if sysfs is optional in any meaningful way any more. I haven't tried running w/i /proc in a few months, it didn't work when I did, but old kernels are old news. -- bill davidsen <davidsen@tmr.com> CTO, TMR Associates, Inc Doing interesting things with little computers since 1979. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
