Subject: gettime: use proper uint64_t types where needed
X-Git-Tag: fio-2.0.14~115
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=ba458c2f1d12c54fb4cfd4918a4e4d72d84b55a4;p=fio.git

gettime: use proper uint64_t types where needed

Windows has 32-bit longs even on 64-bit, so we risk overflowing.
