The branch main has been updated by mav: URL: https://cgit.FreeBSD.org/src/commit/?id=20dc2c4d11ddaa980c491116b65c51ab522028e9 commit 20dc2c4d11ddaa980c491116b65c51ab522028e9 Author: Alexander Motin <mav@FreeBSD.org> AuthorDate: 2023-03-09 15:19:00 +0000 Commit: Alexander Motin <mav@FreeBSD.org> CommitDate: 2023-03-09 15:19:00 +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.
