Subject: Ignore pre-read for FIO_NOIO td
X-Git-Tag: fio-2.19~10
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=736f1188e50f74e7755706cfe40ddcf3e7420ed2;ds=inline

Ignore pre-read for FIO_NOIO td

pre_read_file() should ignore FIO_NOIO (i.e. cpuio) in addition to
FIO_PIPEIO. It does/should fail anyway since FIO_NOIO td is supposed
to have -1 for fd for not supporting any I/O.
