Subject: Default to CS_GTOD if CONFIG_CLOCK_GETTIME isn't defined.
X-Git-Tag: fio-2.0.14~43
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=86e53416e5758d56e950af6cfbe407065ef36879

Default to CS_GTOD if CONFIG_CLOCK_GETTIME isn't defined.

Defaulting the clock source to CS_CGETTIME broke on OS X because it
doesn't have clock_gettime. Use CS_GTOD if CONFIG_CLOCK_GETTIME isn't
defined.
