631  * which can be truncated. This really can foul up an archive. With truncation
633  * truncation the inodes are the same value). We address that by detecting
634  * truncation and forcing a remap of the device field to split truncated
635  * inodes away from each other. Each truncation creates a pattern of bits that
639  * truncation pattern are mapped to the same new device. Two inodes that
640  * truncate to the same value clearly will always have different truncation
642  * device truncation we remap the device number to a non truncated value.
745  *	and device truncation and remap the device as required. Device mapping
768 	 * check for device and inode truncation, and extract the truncated  in map_dev()
780 	 * then find the truncation bit pattern which applies  in map_dev()
802 		 * form of truncation, we do not need a remap  in map_dev()
808 		 * we have truncation, have to add this as a device to remap  in map_dev()
816 		 * truncation pattern of all 0's) continue to map to the same  in map_dev()
818 		 * this device number to the archive with the truncation  in map_dev()
840 		 * found an unused value. If we have reached truncation point  in map_dev()
854 	 * got a new device number, store it under this truncation pattern.  in map_dev()
