a 1000 fold bigger then most people are used to :)


I disagree there is only a little bloat: the current mechanism in place does not scale as NR_CPUS increases, as this thread demonstrates.

Beyond a certain point, on an 8-CPU box, it gets silly. You certainly don't need eight kblockd threads or eight ata threads.
