You might want to check

https://www.kernel.org/doc/html/latest/process/submitting-patches.html

"Describe your changes in imperative mood, e.g. “make xyzzy do frotz” 
instead of “[This patch] makes xyzzy do frotz” or “[I] changed xyzzy to 
do frotz”, as if you are giving orders to the codebase to change its 
behaviour."

For example:

Add examples for the `Either` types.

It looks to me that the default is to add

/// # Examples

followed by some verbose explanation before the test code below.

I ran that on the the target and got:

# rust_doctest_kernel_types_rs_3.location: rust/kernel/types.rs:485
ok 107 rust_doctest_kernel_types_rs_3
