Subject: Fix implicit function declaration on Android
X-Git-Tag: fio-2.2.6~4^2
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=93eeb5582d56fe5e36f455c8de26c302e317fdeb;p=fio.git

Fix implicit function declaration on Android

there's no fio_set_sched_idle in os/os-android.h. copy the one from
os/os-linux.h.

current Android also has posix_madvise.
