The "fuse" in skiplist should match all fuse based filesystems. We pass
the skip_filesystems pointer to tst_get_supported_fs_types() in
lib/tst_supported_fs_types.c. If "fuse" is present there we enable
skip_fuse flag nad pass it to fs_could_be_used() function. In the
fs_could_be_used() we check if filesystem is implemented by fuse and
then skip it accordingly.

When I run the test I see:

...
tst_supported_fs_types.c:165: TINFO: Skipping FUSE based ntfs as requested by the test
...

So likely something else is at play here. Are you sure you are dealing
with a fuse based ntfs or with the kernel based implementation?
