efs-utils is not supported --fake options

[DongZhaoXiong]

fs-1234:/ /home/ec2-user/efs efs _netdev,noresvport,tls 0 0

run command:

mount -fav

/home/ec2-user/efs: successfully mounted

What's the issue here? Are we expecting that the EFS file system to not be mounted with -f/--fake?

[DongZhaoXiong]

I mean that I use the fake option, but the efs filesystem is mounted successfully, not dry run.

What's your use case for the --fake option here? From https://man7.org/linux/man-pages/man8/mount.8.html, "it is mostly for backward compatibility."
