[PATCH 0/4] nvme-blkmq fixes

[Keith Busch]

This fixes some surprise hot plug and error handling cases.

There is still one deadlock when we run out of tags and get stuck in
bt_get, but Jens sent me a test patch that I verfied fixes that when
used with this set.

Keith Busch (4):
  blk-mq: Exit queue on alloc failure
  blk-mq: Export freeze/unfreeze functions
  NVMe: Fix double free irq
  NVMe: Freeze queues on shutdown
