[xfstests-bld PATCH 1/2] test-appliance: fix specifying f2fs mount options in config file

[Eric Biggers]

From: Eric Biggers <ebiggers@google.com>

setup_mount_opts() is supposed to prepend "-o " to the mount options,
but it failed to do so in the case where mount options are specified in
a config file rather than on the command line.  Fix it.

[xfstests-bld PATCH 2/2] test-appliance: add 'encrypt' config for f2fs

[Eric Biggers]

From: Eric Biggers <ebiggers@google.com>

Allow testing f2fs using the test_dummy_encryption mount option,
available with f2fs in kernel 4.17 and later.  E.g.,

    gce-xfstests -c f2fs/encrypt -g auto

This is the f2fs equivalent of ext4/encrypt.
