The branch stable/13 has been updated by mav: URL: https://cgit.FreeBSD.org/src/commit/?id=de0b02cb7b112947191af96dd34e7a95b760019c commit de0b02cb7b112947191af96dd34e7a95b760019c Author: Alexander Motin <mav@FreeBSD.org> AuthorDate: 2023-03-09 15:19:00 +0000 Commit: Alexander Motin <mav@FreeBSD.org> CommitDate: 2023-03-13 13:53:03 +0000 nvmecontrol: Fix default ns create parameters. Instead of passing 0xff's for all unset parameters, prefer reasonable defaults. It is much easier to use it this was without specs in hand.
