Verified that relevant torture test passes in new Samba 4.19.3 build. Will be in 13.1-RC1 when it is released.

Thanks, will it be 13.1-RC.1 or 13.1.0 ?

Ignore previous comment. I was able to reproduce the issue, it’s related to how we handle btime on FreeBSD (not immutable there). I’ll fix, but won’t hit for 13.0-U6.

I’ll need to see full debug of system.
