[PATCH v1 2/4] bitmap: Add bitmap_fill()/bitmap_set() test cases

Andy Shevchenko
2018-01-09T17:25:36Z

Explicitly test bitmap_fill() and bitmap_set() functions.

For bitmap_fill() we expect a consistent behaviour as in bitmap_zero(),
i.e. the trailing bits will be set up to unsigned long boundary.
