I'm under the impression that it is a fix rather than an improvement. However, since it has been stewing for a while, it's clearly not urgent. I don't have anything specific on the bug fix, other than that we're supposed to stop taking those refcounts. Perhaps Sumit, Marco, or Matthew can add something?
It's a long outstanding fix regarding memory page management. The userspace gets informed about this memory API misuse via a warning print incl. a backtrace. This gets triggered only if userspace uses OP-TEE trusted-keys or the OP-TEE EFI variables. Therefore I would like to get it into 7.0 but 7.1 fine too.
Yes, that is clearly a bugfix. I think we'd also want this to be marked 'Cc: stable@vger.kernel.org' as it should also apply to 6.18-LTS and 6.19. Greg tends to also pick up bugfixes that don't have this, but it's generally better to be explicit here, especially when it's not obvious what the impact of the fix is.
I've merge the pull request now. If you think this should be in 6.18-lts and Greg doesn't pick it up by himself, maybe let him know about it.
