This line is too long. Please reflow at 100 characters.

You can also consider this option:

/// Exposes one of the kernel locking primitives. Which one is exposed 
depends on the lock [backend]
/// specified as the generic parameter `B`.
///
/// [backend]: Backend

Hi Ben,

Thanks for the patch! Several notes:

  - Missing commit message -- in general, please check your patches
with `scripts/checkpatch.pl` and please read
https://docs.kernel.org/process/submitting-patches.html.

  - This patch goes on top of the previous one you sent but, in the
kernel workflow, what you are expected to do is send a v2 of your
patch series instead. You can use `-v2` in `git format-patch` for
that.

  - This patch is not just reflowing as the title implies, but it also
changes the style of the link -- is there a reason for that? If yes,
this should be explained.

Cheers,
Miguel

Thank you very much for your feedback, this is really helpful as I'm 
learning the process.

I've submitted a proper v2 of my patch based on your feedback which is 
hopefully much more like what you would expect - please let me know.

Many thanks,

Ben

"iff" is not a typo. Even if it were, it is best to avoid mixing
different types of changes in commits, to keep them as small as
possible (though sometimes there are exceptions).

What about simply:

    [`Backend`]

? (assuming it works).

Cheers,
Miguel

[PATCH v2] rust: lock: Add intra-doc links to the Backend trait

[Ben Gooding]

Add missing intra-doc links to the Backend trait to make navigating the
documentation easier.

We should change the wording to "if and only if" to avoid confusion.
