Check and see if it's still a problem with what I ultimately ended up pushing to Linus. Yes, the way I chose to fix things means that we'll never do more than 2**32-1 blocks at a time with fiemap, but in practice there's a limit to the number of extents that can be returned in a single fiemap call anyway, so in practice this shouldn't be a problem. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
