Re: inserting a Forth-like language into the Linux kernel

[Rick Hohensee <humbubba@smarty.smart.net>]

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.
