[GIT PULL PATCH 0/9] Rust changes for v7.4-rc1

[Andreas Hindborg]

Hi Jens,

I have a number of Rust block layer patches I would ask you to pick for
v7.4. I have collected them into a patch series as well as a pull request
so you can use whatever is easier.

The changes cover

 - Style and formatting changes.
 - Documentation fixes.
 - Fixes for missing trait bounds that can cause API unsoundness.
 - A change to set the owner of the file operations vtable in `GenDisk`.
 - Two bug fixes for the rnull driver.

The following changes since commit df2908090cda368b01ff43709f51890076c56157:
