Hi!
Here is the fifth iteration!. This revision includes a check to validate the
block size in the abstractions rather than in the driver. Also, the `GenDisk`
type state was changed to a builder pattern.
V4 is here [1].
Changes from v4:
- validate block size in abstractions instead of in driver code
- refactor `GenDisk` to builder pattern instead of type state
- refactor `Request::try_end` and `Request::end_ok` methods`
- fix formatting errors
- fix and clarify a number of safety comments
- fix typos in documentation
Thanks to all those who had spare cycles to suggest improvements!
Best regards,
Andreas Hindborg
