The return of the realtime tree

[Posted July 20, 2011 by corbet]

Those who follow the realtime preemption patch set know that it has been stuck on 2.6.33 for some time. With the release of a new patch based on 3.0-rc7, Thomas Gleixner tells us why: the entire series has been reworked and cleaned up, a new solution to the per-CPU variable problem has been implemented, and a nasty bug held up what would otherwise have been a release based on 2.6.38. "The beast insisted on destroying filesystems with reproduction times measured in days and the total refusal to reveal at least a minimalistic hint to debug the root cause. Staring into completely useless traces for months is not a very pleasant pastime." The 3.0-rc7 version of the patch, happily, shows no such behavior.

THANK GOD!!!

(Not that I'm having much trouble getting JACK to play xrun-free using the -bfs kernel on a 6-core, 3.0ghz Phenom II machine.)

I'm sorry, I meant $DEITY. What was I thinking?

Great news :) I'm keeping my fingers crossed.

We just added an amd64 realtime configuration to Debian unstable for Linux 3.0.

What I like about this

What I like about this, is that it looks like these changes are much closer to mainline, which will be easier to merge with mainline.

Everytime out-of-tree-code gets a bigger change of getting merged always makes me happy. :-)
