Yes, so people could see my original submission. Then I've explained the purpose of the forward when asked, I don't see any problem with that.

Between the initial patch and the maintainer's patch there was a private conversation between me and the maintainer (I don't have access to it because I've used my work email and since then I switched companies). I posted my reworked patch only for visibility, since by then they have accepted the maintainer's patch. But I sent the reworked patch in private to the PowerPC maintainer, before sending it to the powerpc mailing list.

Here is the original patch I sent to the Linux kernel security team: https://www.mail-archive.com/linuxppc-dev@lists.ozlabs.org/msg221962.html

Yeah, I think my issue was that I was trying to do this the "C" way and this doesn't fit the Rust ownership model.
