Hi, according to code comments: diff_iterate2 returns the differences between two versions of an image via a callback, which gets the offset and length and a flag indicating whether the extent exists. Now, there are two code paths to calculate diff, one that uses fast-diff/obj-map and the other which asks osds. It appears that only fast-diff code path can set "exists" flag to false in the diff_iterate's callback. Is that the correct assumtion? thanks! -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
