The number of blocks that are marked as reserved, if any, in
this partition. These are typically used to store the in-flash
bad block table (BBT).

+What: /sys/class/mtd/mtdX/offset
+Date: March 2015
+KernelVersion: 4.1
+Contact: linux-mtd@lists.infradead.org
+Description:
+ For a partition, the offset of that partition from the start
+ of the master device in bytes. This attribute is absent on
+ main devices, so it can be used to distinguish between
+ partitions and devices that aren't partitions.
