Hi,


You can use df/mount command to do check, as below:

-----------------------------------------------------------------

[root@Fedora-30-vm linux]# df -h | grep '/tmp'
tmpfs           993M  4.0K  993M   1% /tmp

[root@Fedora-30-vm linux]# mount | grep '/tmp'
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,seclabel)

------------------------------------------------------------------

aio02 uses open(O_WRONLY | O_TRUNC | O_DIRECT | O_LARGEFILE | O_CREAT) to

create test file in default /tmp directory and ****O_DIRECT flag may not 
be supported

by tmpfs so calling open() returns EINVAL.
