I think it (for now) should remain in the few file-systems that are affected to avoid making a new ->i_op right now. If it turns out this is a more commonly need in the future we could do this, but it seems a bit heavy handy just yet given at present. Also, it might turn at that it makes sense to to on-the-fly conversion in the filesystem (where applicable) at some later stage, so this wouldn't be useful there. I assume it's probably hard to convert a large bitmap-based ext4 file to an extent-based one (how large can a transaction be?) but that might not always be the case and it's probably fine for smaller files. > (BTW another option would be to convert old-format files when > accessed, but that has its own set of tradeoffs...) I think doing that where possible makes more sense. As I said above I'm not sure how easy that is to do for all files, but then again fsck could take care of those if prodded. - 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
