Not sure if we understand each other: I mean add "ntfs" and *remove* "fuse",
as "fuse" is now redundant when we whitelist ntfs (see
tst_get_supported_fs_types()), unless there is problem with other fuse
filesystems. I tested with CONFIG_FUSE_FS=m CONFIG_EXFAT_FS=m.

But maybe removing "fuse" should be a separate step.

See above.

See above.
