Linux 6.1 (LTS) confirmed, but no fix for mknod yet

but you’ve written:

I reported an issue with security.syscalls.intercept.mknod misbehaving/not functioning as intended with anything beyond 5.15 LTS some time ago and now I’ve tested it again with the new 6.1 LTS and it still doesn’t work, so I thought I might just mention it again

As far as I understand, something was broken for you after 5.15 LTS kernel, correct? But now you are writing that btrfs worked before, and is working now (with fresh kernels), correct? Then what’s the problem? Where the kernel regression is?
