Linux creator Linus Torvalds announced the release of the 2.6.21 kernel, "if the goal for 2.6.20 was to be a stable release (and it was), the goal for 2.6.21 is to have just survived the big timer-related changes and some of the other surprises (just as an example: we were apparently unlucky enough to hit what looks like a previously unknown hardware errata in one of the ethernet drivers that got updated etc)." Regarding the the dynticks code which was merged in -rc1 [story] he said, "the big change during 2.6.21 is all the timer changes to support a tickless system (and even with ticks, more varied time sources). Thanks (when it no longer broke for lots of people Wink go to Thomas Gleixner and Ingo Molnar and a cadre of testers and coders."
