Yes, that would simplify things greatly for us. Uprobes-as-module has
been working for 3 months or so.* We also wouldn't need the uprobes_data hook.
*Well, it does great when we insmod uprobes.ko and never rmmod it, which
is presumably how SystemTap would use it. "Rmmod uprobes" doesn't clean
things up the way it should, and we need to ref-count the module for
outstanding uretprobe_instances. I'll file a bugzilla on that on
Monday.
