H A D | pci.c | db3cbfff Tue Jan 12 15:41:17 CST 2016 Keith Busch <keith.busch@intel.com> NVMe: IO queue deletion re-write
The nvme driver deletes IO queues asynchronously since this operation may potentially take an undesirable amount of time with a large number of queues if done serially.
The driver used to manage coordinating asynchronous deletions. This patch simplifies that by leveraging the block layer rather than using kthread workers and chaining more complicated callbacks.
