If I use udev to rename my devices, the names aren't going
to match /proc/tty and what ps shows.
It's not as if ps will mislead you. You get "?" if you
redirected stderr or if you lack permission to examine
the /proc/*/fd/* links.
Of course, failing to follow Documentation/devices.txt is
complete foolishness. We have standards you know. The names
are pretty much part of the ABI. Feel free to swap /dev/zero
with /dev/random if you believe otherwise.
The idea behind udev is that the kernel only deals in device
numbers and all naming happens in user space.
For many things, the kernel knows:
$ cat /proc/*/maps | egrep '000[ ].*/dev'
3001e000-30020000 rw-s 90000000 03:0d 2989877 /dev/fb0
3002a000-3004a000 rw-s f0000000 03:0d 2990830 /dev/mem
3004a000-3104a000 rw-s 94000000 03:0d 2989877 /dev/fb0
The kernel only needs to remember, by keeping a dentry around.
Not that a devices.txt-compliant devfs wouldn't kick ass...
