From: Binglei Wang <[email protected]>
Implement the kretprobes on riscv arch by using rethook machenism
which abstracts general kretprobe info into a struct rethook_node
to be embedded in the struct kretprobe_instance.
Acked-by: Masami Hiramatsu (Google) <[email protected]>

Binglei's patches do not seem to make it to the linux-riscv list, so
blindly resending on their behalf, with Masami's ack from v8 added.

Thanks for your resending.
What to do next is just to wait patently, right ?

Yup.. You'll get at least one email when it gets applied.
It's in patchwork [0] so it should not get forgotten about.
