Subject: [PATCH 0/3] block: model freeze/enter queue as lock for lockdep

Hello,

The 1st patch adds non_owner variants of start_freeze/unfreeze queue
API.

The 2nd patch applies the non_owner variants on nvme_freeze() & nvme_unfreeze(). 

The 3rd patch models freeze/enter queue as lock for lockdep support.


Ming Lei (3):
  blk-mq: add non_owner variant of start_freeze/unfreeze queue APIs
  nvme: core: switch to non_owner variant of start_freeze/unfreeze queue
  block: model freeze & enter queue as lock for supporting lockdep
