Subject: [PATCH 00/25] Updates to lightnvm and pblk

Hi,

A bunch of patches for the lightnvm subsystem and pblk.

The first part is preparation patches for the 2.0 revision of the
specification. This includes removing the null_blk implementation
and killing the rrpc implementation, which used already deprecated
definitions from the 1.2 revision. Then a couple of patches of
general clean up and then finally provide a path to support both
the 1.2 and 2.0 revisions simultaneously.

The second part is fixes for the lightnvm subsystem, pblk, and
new features that include ioctl support for instantiating pblk
with specific overprovisioning percentage and adding iostat
support.
