 I had ran a lot(10~15) of my program to manipulate a file when the
 race condition appeared.The program do the program do mount(),
 open(), close() and unmount() each time.
 
 Perhaps,the condition may depends on a environment because
 it was appeared on ESXi 6.7, but not appeared on qemu on Fedora 30.
