[PATCH 0/7] Misc volume patch set part2

[Anand Jain <anand.jain@oracle.com>]

As the last set if the pull wasn't integrated due to its pending
review corrections. Here, I have done them (not much except for adding
comments and function renames) and so sending it again. Also
this set clubs other independent patches which are in the mailing list.
I am explaining the changes of the individual patches in its change list.
And most of it still remains at v1.
