Therefore, create a new set of macros KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ that compare memory blocks until a determined size. In case of expectation failure, those macros print the hex dump of the memory blocks, making it easier to debug test failures for memory blocks. The v7 has some formatting changes on the first patch and it was rebased on top of the mainline (due to 7089003304c6). The first patch of the series introduces the KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ. The second patch adds an example of memory block expectations on the kunit-example-test.c. And the last patch replaces the KUNIT_EXPECT_EQ for KUNIT_EXPECT_MEMEQ on the existing occurrences.
