You're looking for the ecryptfs_xattr mount option. It is an
eCryptfs-specific mount option, so we try not to pollute the global
mount option namespace by using the "ecryptfs_" prefix.

The GPG key module isn't fully implemented so it returns an error during
initialization. You can ignore this.

If you installed ecryptfs-utils with your distro's package manager,
you may want to let the package maintainer know that there is no need to
build that key module at this time. If you built ecryptfs-utils from
source, don't pass --enable-gpg to the configure script.
