[linux-lvm] LVM2 design document

[Kumar amit mehta]

Hi,

I'm trying to learn LVM2 in detail, and for that I've cloned the git
repo and have been going through the sources for sometime, but I've not
made a significant progress so far, hence It would be very much helpful
to me if you can please point me to the design document(if available) 
of LVM2, which gives a fair high level idea behind the design and the
important data structures.
