Its about time someone did it right. Special > bonus if you can do it in a way that it does not slow down. If cpu > is free, compress, if it is busy, just write it straight to disk. So if I decide that the cpu is busy (because something is asking me to write the cpu is clearly doing something and hence busy), then I can skip compression and just write to disk. So by that definition ext4 already does compression. What a simple project. :) Did you mean it ought to come back and do the compression later? Is it possible that for some data compressing it and writing will take less time than not compressing it and writing it to disk? -- Len Sorensen - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
