Ahem! % ll fs/proc/proc.o fs/devfs/devfs.o -rw-r--r-- 1 rgooch computer 39171 Feb 17 16:16 fs/devfs/devfs.o -rw-r--r-- 1 rgooch computer 47737 Feb 17 16:16 fs/proc/proc.o
Looks to me that devfs is more lightweight. On a typical workstation (i.e. bigger than an embedded machine), add a few pages of data to that.
So in fact, devfs is pretty lightweight. I'm not sure why people keep saying otherwise. I've published numbers a couple of times before.
