[GIT PULL] Lightnvm fixes and updates for 4.5-rc1

From: Jens Axboe
Date: Thu Jan 21 2016 - 16:22:43 EST


Hi Linus,

This should have been part of the drivers branch, but it arrived a bit
late and wasn't based on the official core block driver branch. So they
got a small scolding, but got a pass since it's still new. Hence it's in
a separate branch.

This is mostly pure fixes, contained to lightnvm/, and minor feature
additions.

Please pull!
