Try a "cat /proc/net/dev" and then tell me no ill side effects :) No, at
this point, your internal kernel device list (or the proc representation of
said list) is nice and toasty. Fine if you don't need to touch the devices.
Fine if you don't receive any packets for a device that's toasted. Sucks
in terms of general appearance. The problems I had with this and with
processes "disappearing" from the process table (/proc filesystem didn't
list them, but even though the directory wasn't listed you could still cd
into the directory and find information on them) co-incided with the final
release of 2.0.30. Dave's pre-2.0.30-2 patch does not have this problem.
Somebody should probably do a diff between Dave's last pre-2.0.30 tree and
Linus' official 2.0.30 tree to see where things might have gone wrong.
