Cool! Thanks for publishing a specification. This will help everyone
understand the code.
+=== Dirty bitmaps feature ===
+
+This feature provides a way of storing dirty bitmaps in the image. The fields
+of its data area are:
+
+ 0 - 7: size
+ The bitmap size, should be equal to disk size in sectors.
+
+ 8 - 23: id
+ An identifier for backup consistency checking.
+
+ 24 - 27: granularity
+ Bitmap granularity, in sectors. I.e., the number of sectors
+ corresponding to one bit of the bitmap.
Does this need to be a power of 2?
