The branch stable/14 has been updated by np: URL: https://cgit.FreeBSD.org/src/commit/?id=b9f7a09c490f4eb6b9c179d1dfd756e236494998 commit b9f7a09c490f4eb6b9c179d1dfd756e236494998 Author: Navdeep Parhar <np@FreeBSD.org> AuthorDate: 2024-09-24 23:28:29 +0000 Commit: Navdeep Parhar <np@FreeBSD.org> CommitDate: 2024-10-21 17:14:39 +0000 cxgbe(4): Clobber all tracer state on stop and redo only traceq on restart. Tracers have to be recreated after a restart but that's okay given that they are used for debugging only.
