-	/* TODO: currently the fastmap code assumes that the fastmap data
-	 * structures are created only by the kernel when the kernel attaches
-	 * an fastmap-less image. However, this assumption is too limiting and
-	 * for sure people will want to pre-create UBI images with fastmap
-	 * using the ubinize tool. Then they wont have to waste a lot of time
-	 * waiting for full scan and fastmap initializetion during the first
-	 * boot. This is a very important feature for the factory production
-	 * line where every additional minute per device costs a lot.
-	 *
-	 * When you are attaching an MTD device which contains an image
-	 * generated by ubinize with a fastmap, you will not know the
-	 * 'bad_peb_count' value. Most probably it will contain something like
-	 * -1. The same is true for the per-PEB information in the fastmap - it
-	 * won't tell which PEBs are bad. So we need to detect this and iterate
-	 * over all PEBs, find out which are bad, and update 'ai' here. */
