The branch main has been updated by zlei: URL: https://cgit.FreeBSD.org/src/commit/?id=35b3be81f1d9fe38457d9137bef7a2875d24e2c8 commit 35b3be81f1d9fe38457d9137bef7a2875d24e2c8 Author: Zhenlei Huang <zlei@FreeBSD.org> AuthorDate: 2023-10-09 10:30:22 +0000 Commit: Zhenlei Huang <zlei@FreeBSD.org> CommitDate: 2023-10-09 10:30:22 +0000 proc: Add sysctl flag CTLFLAG_TUN to loader tunable The sysctl variable 'kern.kstack_pages' is actually a loader tunable. Add sysctl flag CTLFLAG_TUN to it so that `sysctl -T` will report it correctly. No functional change intended. Note that on arm64 the thread0 stack size can not be controlled with it, kib@ suggested that arm64 maintainers can fix it eventually so let's enable it also on arm64 right now.
