The branch stable/13 has been updated by zlei: URL: https://cgit.FreeBSD.org/src/commit/?id=0007ba082c3353f0c545e5dcf328ce30d74c5ab7 commit 0007ba082c3353f0c545e5dcf328ce30d74c5ab7 Author: Zhenlei Huang <zlei@FreeBSD.org> AuthorDate: 2023-10-09 10:30:22 +0000 Commit: Zhenlei Huang <zlei@FreeBSD.org> CommitDate: 2023-10-12 04:19:37 +0000 mbuf: Add sysctl flag CTLFLAG_TUN to loader tunables The following sysctl variables are actually loader tunables. Add sysctl flag CTLFLAG_TUN to them so that `sysctl -T` will report them correctly. 1. kern.ipc.mb_use_ext_pgs 2. kern.ipc.nmbclusters 3. kern.ipc.nmbjumbop 4. kern.ipc.nmbjumbo9 5. kern.ipc.nmbjumbo16 6. kern.ipc.nmbufs No functional change intended.
