>Description:
I run legacy setup of FreeBSD 4.11 inside jail under 7.4-STABLE,
it runs just fine but kernel spams dmesg buffer with prints:
WARNING: userland calling deprecated sysctl, please rebuild world
It should use log() and not printf() so the message may be filtered out.
Perhaps, this message may be skipped altogether if options COMPAT_4X is
used.
>How-To-Repeat:
I do not know what 4.11 binary calls old sysctl.
