To this point CTLFLAG_TUN was only important for read-only sysctls to give user a hint that the given sysctl can be changed via loader tunable on boot only (or on module load via kenv(1)). Your change makes it useful to also mark read-write sysctls as tunables and I suspect there is huge number of such sysctls that have no CTLFLAG_TUN flag. --=20 Pawel Jakub Dawidek http://www.wheelsystems.com FreeBSD committer http://www.FreeBSD.org Am I Evil?
