Hi all,

This is part of a hackathon organized by LKCAMP[1], focused on writing
tests using KUnit. We reached out a while ago asking for advice on what
would be a useful contribution[2] and ended up choosing data structures
that did not yet have tests.

This patch adds tests for the llist data structure, defined in
include/linux/llist.h, and is inspired by the KUnit tests for the doubly
linked list in lib/list-test.c[3].

It is important to note that this patch depends on the patch referenced
in [4], as it utilizes the newly created lib/tests/ subdirectory.
