Commit Message

Tobin C. Harding April 5, 2019, 1:58 a.m. UTC 
We just added a new C header file for use with test modules that are
intended to be run with kselftest.  We can reduce code duplication by
using this header.

Use new kselftest header to reduce code duplication in test_printf and
test_bitmap test modules.
