Kernel processes can be niced? Nice :) So, for example, in theory I could renice a geli thread that I don't want to eat much of my CPU from the userland? > The AIO threads need to be processes because each of them needs > a different address space that can be hacked to cover the address space of the > process they are working for.

So, mostly cosmetics :) (don't get me wrong, I have nothing against kthreads<->kprocs :) )Received on Mon Oct 22 2007 - 23:16:11 UTC
