Author: cem Date: Sat Jun 13 03:04:40 2020 New Revision: 362141 URL: https://svnweb.freebsd.org/changeset/base/362141 Log: Flip kern.tty_info_kstacks on by default It's a useful debug aid for anyone using Ctrl-T today, and doesn't seem to be widely known. So, enable it out of the box to help people find it. It's a tunable and sysctl, so if you don't like it, it's easy to disable locally. If people really hate it, we can always flip it back.
