SubjectRe: kernel structures 2.0.29->2.0.30

I think this is COMPLETELY unacceptable for a _SUPPOSEDLY_ stable
release.

There are cases where serious performance problems, bugs, and security
holes need to change these structures in order to do the fix at all.
There are some vendors out there who will try to not do the fix just
to keep all the third part vendor drivers from breaking (I'm not
mentioning any names) but this can get out of control and does more
harm than good.

On another issue, the fact that things which stick their noses into
kernel memory like lsof even exist, is a bad thing in itself. If the
facilities completely necessary for such a tool do not exist in procfs
as it exists now, the new features necessary should be added so that
there are no common programs which need to look at the kernels
internal data structures via kmem at all.
