Hi!
Rebased on v6.10-rc1 and implemented a ton of improvements suggested by Benno. v2 is here [2]
Changes from v2:
- implement `atomic_relaxed_op_return` in terms of `AtomicU64::fetch_update`.
- update `Request` docs with state tracking info
- link all types in docs
- add invariant to `TagSet`
- do not unwrap pin in `TagSet::drop`
- remove references to `try_ffi_init` from comments
- numerous typo fixes
- code formatting fixes
- remove remote completion logic
- move `gen_disk::try_new` into `GenDisk` impl
- make `GenDiskState` sealed
- add a default state for `GenDisk`
- conditionally call `del_gendisk` on `GenDisk` drop
- move `add_disk` into `init` functon in rnull module
- improve error message in request completion assertion
- rebased on v6.10-rc1
Best regards,
Andreas Hindborg
