This series adds tests and docs for Rust kernel components:
Patch 1 adds KUnit tests for allocator alignment guarantees.
Patch 2 documents KVec::as_slice with a usage example.
Patch 3 simplifies KVec test module naming convention.

Both patches are co-developed with Geliang Tang. Based on [1].
Tested on x86_64 using KUnit.

Changelog:
v7:
Updated according to the comments of Miguel.
v6:
According to the comments of Danilo, updated test for allocator.rs
and allocator rebase onto [1].
v5:
According to the comments of Danilo, change to use generic struct and
allocator Generics in allocator.rs.
v4:
According to the comments of, add the error check for push.
v3:
According to the comments of Danilo and Boqun, move KVec test to doc
example and move VBox to allocator unit tests.
v2:
According to the comments of Danilo, updated the commit to samples the
usage of VBox and KVec.

Hui Zhu (3):
  rust: allocator: add KUnit tests for alignment guarantees
  rust: alloc: kvec: add doc example for as_slice method
  rust: alloc: kvec: simplify KUnit test module name to "rust_kvec"

Applied to alloc-next, thanks!

This series looks good to me from a KUnit perspective. I've also
tested it out across a bunch of architectures (UML, x86_64, arm,
arm64) with no problems.

A few minor notes:
- You should squash patch 3 into patch 1: there's no need to introduce
the test with one name only to rename it in a later patch.
- The link to [1] is missing in this cover letter. (But at least the
test fails nicely without it!)

Otherwise, looks good!

The whole series is:

The test introduced in patch 1 is not the one renamed in patch 3. :)
