Subject: Add generic arch include header
X-Git-Tag: fio-1.37~8
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=fa77073a574c3b322529fe11c4af16eed1667079;ds=inline

Add generic arch include header

For a newer glibc, this should work (as we don't need private
splice defines, for instance).
