This patch series is a mashup of cleanups, bugfixes and feature additions for
the Rust XArray abstractions.
- Patch 1 starts by fixing minor formatting issues and bringing use
statements up to date with the new coding guidelines.
- Patch 2-3 add some minor convenience functionality.
- Patch 4 adds an abstraction for the C `xa_state` structure. This is a
prerequisite for all the subsequent patches.
- Patch 5 fixes a double lock error in `xarray::Guard::load`.
- Patch 6 is a simplifying refactor of `xarray::Guard::load`.
- Patch 7 adds two new methods for finding items with keys that are larger
than a given integer.
- Patch 8-9 add the new entry API with preloading.
- Patch 10 fixes a lockdep bug caused by reusing the same static key.
I am sorry for the mashup, but I think these changes are easier to handle
in a single series rather than individually.
The feature additions in this series are dependencies for the rust null
block driver, most of which is still downstream.
Best regards,
Andreas
