Hi all,

as Ewan raised the issue that we are suffering from a buffer-bloat
problem when using the round-robin I/O scheduler here are additiona
I/O schedulers to improve the situation.
The schedulers are untested, and are compile-tested only.
I just putting them out here as I had several requests for them;
I'm happily improving them upon feedback.

Hannes Reinecke (2):
  nvme-multipath: add additional iopolicies
  nvme-multipath: add 'latency' iopolicy
