[Minios-devel] [UNIKRAFT PATCH v3 0/6] Unikraft Block API

[Roxana Nicolescu <nicolescu.roxana1996@xxxxxxxxx>]

Introduces the Unikraft Block API, that acts as a generalized interface
between block drivers and filesystems implementations (or low-level block
applications).

Using the function definitions in blkdev_core.h, the driver should
include blkdev_driver, implement the functions in uk_blkdev_ops and
fill some fields from uk_blkdev.
The user-facing part of the API is in blkdev.h. The layer above can use
these functions to configure block devices, as well as send and receive
sector-wide requests.
The read/write/flush operations abstraction is defined in blkreq.h.
Requests can be asynchronous or synchronous and the user must set a
proper callback for each async operation.
The API has multi-queue support and event dispatching support as well,
which is configurable with or without bottom-half threads.

Changes since v2:
- Added comments to functions.
- Changed naming and data types of some variables.
- Changed return type from void to int to forward errors.
