might be better to keep this state in the user_ns itself, would
avoid kzalloc below.
thought about, but hesitated to touch user_ns. might not be the best
idea when having p9caps as module (OTOH, doesn't need to be a module)
the whole thing might become a bit more complex when introducing
plan9-like unprivileged mount operations. haven't sorted out how to
do that yet.
Would it be worth doing any privilege checking here?
Which ones should I check ?
