Subject: Re: Does the kernel page the CFS's red-black tree nodes?

The kernel doesn't page its own data structures (there a couple of
exceptional cases). That avoids the entire nightmare of trying to have
partly paged kernels, the resulting priority inversions and all the other
horrors you can get plus the big overheads from it.
