From: Klaus Jensen <k.jen...@samsung.com> The nvme device currently uses an ad-hoc approach to tracking AIO completion when a request results in multiple issued AIOs.
This series convert those operations (DSM, Copy, Flush and Zone Reset) to use "proper" QEMU AIOCB processing instead. This requires more code, but the end result of this is that we gain proper cancellation support (something that the device would not do correctly in the existing ad-hoc approach, and something that would have required more code anyway). This series makes SQ deletions "just work" and allows Abort to be implemented such that it actually does something. Marking RFC, since I've not really done anything with QEMU AIOs and BHs on this level before, so I'd really like some block-layer eyes on it.
