+Subject: list: test: Add a test for list_is_head()
+
+From: David Gow <davidgow@google.com>
+
+commit 37dc573c0a547e1aed0c9abb480fab797bd3833f upstream.
+
+list_is_head() was added recently[1], and didn't have a KUnit test. The
+implementation is trivial, so it's not a particularly exciting test, but
+it'd be nice to get back to full coverage of the list functions.
