I think uprobe_clear_state() should be removed from fork.c entirely,
made 'static', and then we'd have
area->xol_mapping.close = uprobe_clear_state;
in __create_xol_area() instead (ok, the arguments change, instead of
looking up "mm->uprobes_state.xol_area", it would get it as the vma
argument)
That's how it should always have been, except we didn't have a close() function.
Hmm?
