BTW, is this (batched register/unregister APIs) something you'd like
to use from the tracefs-based (or whatever it's called, I mean non-BPF
ones) uprobes as well? Or there is just no way to even specify a batch
of uprobes? Just curious if you had any plans for this.

No, because current tracefs dynamic event interface is not designed for
batched registration. I think we can expand it to pass wildcard symbols
(for kprobe and fprobe) or list of addresses (for uprobes) for uprobe.
Um, that maybe another good idea.

I don't see why not. The wild cards were added to the kernel
specifically for the tracefs interface (set_ftrace_filter).

Nice, I'd be happy to adjust batch API to work for that use case as
well (when we get there).
