I'll include that fix in v2. [0]: https://docs.kernel.org/bpf/kfuncs.html#creating-a-wrapper-kfunc This is also reminding me to send out the v2 for [1]. I'll do that after I take care of another few small things I've been putting off. [1]: https://lore.kernel.org/lkml/20230106195130.1216841-3-void@xxxxxxxxxxxxx/T/ Thanks, David
