that's without CONFIG_SMP, right? :-) On SMP they are about net break
even:
text data bss dec hex filename
26535 4173 24 30732 780c kernel/sched.o-2.6.22
28378 2574 16 30968 78f8 kernel/sched.o-2.6.23-git
(plus a further ~1.5K per CPU data reduction which is not visible here)
btw., here's the general change in size of a generic vmlinux from .22 to
.23-git, using the same .config:
text data bss dec hex filename
5256628 520760 1331200 7108588 6c77ec vmlinux.22
5306918 535844 1327104 7169866 6d674a vmlinux.23-git
+50K. (this was on UP)
In any case, there's still some debugging code in the scheduler (beyond
SCHED_DEBUG), i'll work some more on reducing it.
