Hello Jens,
Multiple block drivers need the functionality to stop a request queue
and to wait until all ongoing request_fn() / queue_rq() calls have
finished without waiting until all outstanding requests have finished.
Hence this patch series that introduces the blk_mq_quiesce_queue()
function. The dm-mq, SRP and NVMe patches in this patch series are three
examples of where these functions are useful. These patches have been
tested on top of kernel v4.9-rc1. The following tests have been run to
verify this patch series:
- Mike's mptest suite that stress-tests dm-multipath.
- My own srp-test suite that stress-tests SRP on top of dm-multipath.
- fio on top of the NVMeOF host driver that was connected to the NVMeOF
target driver on the same host.
- Laurence verified the previous version (v3) of this patch series by
running it through the Red Hat SRP and NVMe test suites.
This looks pretty good, I'll run some testing on it tomorrow and do a
full review, hopefully we can get it applied sooner rather than later
for the next series.
