What does this mean for the cleancache hooks? Are they still > useful? Wow. F***ing incredible. Pekka, you'd best leave the politics to Andrea. He's _much_ better at it. No, I haven't stopped, though I may be pausing to lick my wounds. No it's not dead yet. Yes, the cleancache hooks are still useful, so narrow-minded anti-Xen vultures can go circle elsewhere. Since my attempt at gracefully ending the discussion with poetry has been ruined, I might as well spell it out: "Crash test dummy folds": (1) Andrew, I'm warning you (from the first crash test dummy) that the new process may be too heavy handed and corruptible. (2) I've taken enough beatings for now, thank you. "KVM mafia wins" : If one reads between the many (far too many) lines of this discussion, and as further evidenced by Pekka's reply, the anti-Xen crowd has been losing too many battles recently, is damn well not going to lose this one, and would like by any means possible to reverse previous losses. People, can't we just get along? "Innovation cries": I'm expressing sadness that a very innovative and elegant approach to a very hard problem, that began Xen-specific but seems to have lots of interesting uses, is being blocked for political reasons. I'm not denying that there is plenty of work still to be done, just arguing that this can best be explored as a community project... and that's not going to happen by conveniently ignoring the most mature user (Xen) because one has a personal or corporate vendetta against it. Frontswap should be in-tree. For anyone familiar with the American political system, frontswap has been blocked by a filibuster. I won't be responding to further posts on this topic for awhile, for health reasons.
