Most of the scary stuff (new libata pata drivers etc), we'd keep off, so things shouldn't be too bad. The timer changes for tickless are probably the only remaining scary thing. For that we have a few choices.
- Leave NO_HZ off. Feature parity with FC6, though the code has still changed, and may still find regressions. Probably the safest option.
- Turn NO_HZ on. Early preview of F7 features, saves power yadayada, may find new bugs. (Gets us that nice fuzzy 'f6 bugs are f7 bugs' bonus though)
what kind of bugs would this trigger? crashes? or "only" some weird timer/clock issues?
all sorts of things rely on timers, so it could manifest itself in any number of ways.
if this is done does this also mean that we can backport x86_64 tickless for F7 when its ready?
Given its still not upstream, it'll likely be a while before it lands in FC6. It'll get backported to F7 first after GA, but first it needs to land in Linus' tree.
