New Revision: 325316
URL: https://svnweb.freebsd.org/changeset/base/325316
Log:
Add benchmark for getresuid(2) - three pointers, although only "output" ones,
and quite lightwait.
The purpose of this commit, and the previous one, is to be able to measure
overhead of pointer arguments - in case you're running a strange architecture
where pointers and integers are quite different things at the hardware level.
