Subject: [PATCH 2/3] bitmap: convert self-test to KUnit
Convert the bitmap() self-test to a KUnit test.
In the interest of keeping the patch reasonably-sized this doesn't
refactor the tests into proper parameterized tests - it's all one big
test case.
Signed-off-by: Tamir Duberstein <tamird@...il.com>
