[PATCH 0/2] nvme: fix hang in path of removing disk

[Ming Lei]

The 1st patch fixes one race between resettting failure and remove.

The 2nd patch avoids hanging in del_gendisk() if del_gendisk() waits
for these submitted writeback requests.

Keith, about the 1st patch, as we talked, there are two directions for
fixing the 1st issue, I know you may be working towards treating this
reset failure as controller dead, and not completed yet. But if
nvme_remove_dead_ctrl() is needed in any one of reset failure path,
this patch is still required. Seems both two directions aren't
contradictorily.
