New subject: [ion] 13113: Share duplicated Rtl code. I've taken care to use the most recent code, so now ntoskrnl can also do environment string expansion.

I also tried merging the two once. It seemed they both had stuff impl.
that the other hadnt. Did you merge or did you take the best one?
And env. str. exp. crash in kmode Windows, at least with NULL
Environment. This is because the system process has no PEB. It could
work when passing something in Environment, but have never seen it done.
Env. str. exp. is said to be of no use in kmode anyways...
