I believe this is the patchset you are referring to:

https://lore.kernel.org/linux-security-module/20240207124918.3498756-1-kpsingh@kernel.org

It wasn't that the patchset was accepted or rejected, it is still in
the review queue as there are higher priority items being kicked
around in the LSM space at the moment.  It also wasn't a pure bug-fix
or feature patchset/patch, which muddied things a bit.
