Subject: Only expose fadvise_hint=noreuse if supported
X-Git-Tag: fio-3.35~43
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=638689b15af35bd746f9114a3e8895e7a983ed83;p=fio.git

Only expose fadvise_hint=noreuse if supported

At least OSX doesn't have this option or define, just make it
available if it's there on the platform we're building on.

Fixes: eb314e7072a0 ("fio: add support for POSIX_FADV_NOREUSE")
