Hi all,
We are working on RBD persistent writeback cache which caches data on
block devices.
Currently, we operate the cache device using the driver in BlueStore:
src/os/bluestore/KernelDevice.
Meanwhile, we may need to use other block device drivers in BlueStore.
So we need to reuse these codes in librbd.
Thanks to Jason who gave us some suggestions. And Changcheng submitted
a PR about this work.

Welcome for more suggestions and comments.
Best wishes
Lisa
