Subject: [PATCH] Filesystem: Add support for Amazon EFS mount helper
mount.efs, the mount helper for Amazon Elastic File System (EFS)
provided by amazon-efs-utils [1], is a wrapper for mount.nfs4. It offers
a number of AWS-specific mount options and some security improvements
like encryption of data in transit.
This commit adds support by treating an fstype=efs like fstype=nfs4 for
the most part.
Resolves: RHBZ#2049319
