Needs a proper commit message - wrap it at 72 columns,  change log
should be placed below the --- devider, not be part of hte commit
message.

Test numbers do not need to be unique across all test directories,
just unique within the tests/btrfs directory.

Just cut the file name out. No need for filtering at that point...

which means the golden output is broken, despite the filtering

You should test your patches before posting ;)

FWIW, this is why you should simply cut the filename completely out
like we do elsewhere....
