[PATCH v2 0/3] fixes for LightNVM

[Wenwei Tao <ww.tao0320@gmail.com>]

Hi Matias
A couple of fixes based on 4.4rc2

Patch 1: the locking issue

move codes 'register with device with a supported manager'
into a funtion.
But I think iterate over a list to register nvm device
with a manger is not a good idea, since we can blocked
in manager's register_mgr function while holding nvm_lock.

Patch 2: handle targerts when underlying devices were removed

free dev when exited

call target type's exit function when target creation was aborted
due to nvm device exit.

Patch 3: change the interface between nvme and lightnvm

remove the unnecessary nvme_ns->type set to zero

Wenwei Tao (3):
  lightnvm: missing nvm_lock acquire
  lightnvm: handle targets when corresponding nvm device exit
  nvme: change the interface between nvme and lightnvm
