New Revision: 207879
URL: http://svn.freebsd.org/changeset/base/207879
Log:
MFC: r207330, r207620
- Remove dead code. Calculated greatest common divisor was not used at all.
- Prefer u_int32_t over unsigned int to make its intention more clearer.
- Move the function to a header file and make it a static inline function.
