The branch main has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=488c498b099e3f48db4048833d2b0d03d7bed3e1 commit 488c498b099e3f48db4048833d2b0d03d7bed3e1 Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2022-12-21 18:46:06 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2022-12-21 18:46:06 +0000 Disable errors for -Wnonnull for the kernel for GCC 12.
