[PATCH v1 0/2] Add Delta::to_jiffies_timeout() with tests

[FUJITA Tomonori <tomo@flapping.org>]

From: FUJITA Tomonori <fujita.tomonori@gmail.com>

The first patch is new. It adds an example and a KUnit test for
Delta::as_millis_ceil(), which Miguel asked for [1].

The second patch was previously posted as patch 4 of [2]; patches 1-3
of that series have been applied. It has been reworked to fix the bug
Miguel reported [1]: on 32 bit with HZ=1000, to_jiffies_timeout()
could return a value larger than MAX_JIFFY_OFFSET.

Both patches follow the format agreed in [3]: the examples show the
behaviour, while the boundary inputs live in `#[test]` KUnit tests, with the
magic numbers as named constants local to the test module rather than part
of the exported API.
