This test doesn’t work with compat=0.10 (because we can’t store a
non-default compression type there) or data_file (because those don’t
support compression), so those options should be marked as unsupported.

(It does seem to work with any refcount_bits, though.)

Could I ask how to achieve that?
I can't find any _supported_* related.


It’s _unsupported_imgopts.

Test 036 is an example of this.
