kspamd/H3sm is now making continuous writes to tty1 from an in-kernel thread. It was locking on a write to /dev/console by init, so I made /dev/console a plain file. This is after hollowing out sys_syslog to be a null routine, and various other minor destruction.
I am now typing at you on tty4 or so while the kernel itself sends an endless stream of d's to tty1. It will scroll-lock and un-scroll-lock, which is how I can tell it's not just a static screen of d's.
I don't know about H1 S&M, but the ability to open a tty normally directly into kernelspace may prove popular, particularly with a Forth on that tty in that kernelspace. Persons with actual kernel clue may want to look at allowing /dev/console users and an in-kernel tty user to play nice. For my purposes I'll do without a real /dev/console and syslogging for now.
Now I get to find out how many worlds of trouble I didn't foresee in _reading_ a tty from the kernel :o)
If someone knows of another example of interpreter-like behavior directly in a unix in-kernel thread I'd like to know about it.
