[PATCH] preemptive kernel for 2.4.19-pre7-ac4

[Robert Love]

The preempt-kernel patch for 2.4.19-pre7-ac4 is now available at

	http://www.kernel.org/pub/linux/kernel/people/rml/preempt-kernel/v2.4/preempt-kernel-rml-2.4.19-pre7-ac4-1.patch

and

	http://www.tech9.net/rml/linux/

There are no notable changes; just the (extensive) resync against all
the scheduler changes that went into 2.4.19-pre7-ac3.  Enjoy,

	Robert Love

... applies to -pre8-ac1 as well. Safe to use?

I'd presume so, pre8-ac1 is a compilation fixes release, as stated in the 
changelog.

Yep.  I sent Alan a few more scheduler updates - if he puts them in
pre8-ac2, that may break the diff but still nothing incompatible. 
Always assume (with most patches, really) that if it applies, it is
fine.

An exception would be things like lock-break or low-latency that assume
intricate knowledge of the locking and calling semantics of functions. 
If they apply, they should compile and boot, but a deadlock may lurk. 
This is partly why these solutions are horrible to maintain or get right
and the preemptible kernel is a wiser long-term solution to latency and
such.

 What about lock-break for the -ac series? Or does this conflict with rmap 
and/or O(1)?

Speaking from experience, it's trivial to port it to either of those, or
a combination of both.
