Yeah, I found it:
http://lkml.org/lkml/2003/7/10/345
I think that if /proc/sys could be broken out as a separate filesystem, and it
was small and simple, the embedded people would probably be happy. Is your
patch significantly smaller than such a filesystem would be? (Keeping in
mind that the smallest thing you can do is run from initramfs, and I think
that's pulling in libfs already...)
