The branch stable/13 has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=e3212b779ae2938428e087ac05c52e484cf2a6c2 commit e3212b779ae2938428e087ac05c52e484cf2a6c2 Author: Mark Johnston <markj@FreeBSD.org> AuthorDate: 2024-01-04 13:25:05 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2024-01-11 14:33:15 +0000 linprocfs: Avoid using a sysctl to get the CPU model string This will fail if the reading process is in capability mode. Just copy the string directly.
