test-bitmap: add test for bitmap_set
Add a test for bitmap_set. There are three cases: * Both start and end is BITS_PER_LONG aligned * Only start is BITS_PER_LONG aligned * Only end is BITS_PER_LONG aligned Signed-off-by: Wei Yang <richardw.yang@linux.intel.com> Message-Id: <20190718010456.4234-3-richardw.yang@linux.intel.com> Reviewed-by: Peter Xu <peterx@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
