The branch stable/13 has been updated by avg: URL: https://cgit.FreeBSD.org/src/commit/?id=f0ed49921c2891733b7ee65679a8dcba5398e3b6 commit f0ed49921c2891733b7ee65679a8dcba5398e3b6 Author: Andriy Gapon <avg@FreeBSD.org> AuthorDate: 2021-12-24 09:38:38 +0000 Commit: Andriy Gapon <avg@FreeBSD.org> CommitDate: 2024-02-17 19:22:08 +0000 dtrace: make 'ring' and 'fill' policies imply 'noswitch' flag This should disable allocation of the second per-CPU principal buffer which is never used. This will also enable additional asserts for buffers that are never switched.
