From: Andreas Hindborg <a.hindborg@xxxxxxxxxxx> 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!
