Minor nit: seeing that there's only one path to that return, I would
rather turn it into
	return n;
and dropped the assignment to ret a few lines above.  Anyway, that's
trivially done when applying...

Anyway, who's carrying fscontext-related stuff this cycle?  I've got
a short series in that area, but there won't be much from me around
there - a plenty of tree-in-dcache stuff, quite a bit of mount-related
work, etc., but not a lot around the options-parsing machinery.

Christian, do you have any plans around that area?
