rbd: bitmaps for tracking object existence
Added by Josh Durgin about 11 years ago.

Description
This would improve layered image performance, and enable quick, conservative usage for an image. It should be possible to add to an existing format 2 image.
I was thinking this weekend of creating this issue exactly.
Are you envisioning keeping these with the image header?
Even without it I could keep an internal bitmap of what
exists in the kernel client, at least until a flatten
operation is detected.
Also, I wonder at what point it becomes worthwhile to
use something different from bitmaps (such as extents
that define entire ranges of existent or non-existent
objects).
