Couldn't we use ~PER_MASK here instead of PER_INHERIT?  That would
mean we wouldn't have to modify include/linux/personality.h, and we
wouldn't have to keep updating PER_INHERIT as more flags get added.

(Nice patch description, BTW.  Thanks.)

Paul.

Yeah, ~PER_MASK will work fine.  I used PER_INHERIT first because I
was not sure if there were values that should not be carried forward.
I will have an updated patch out shortly.
