Your unique, consistently failing test cases for all file systems suggest 
that you have a buggy private kernel or some other individual issue in your 
test environment.

You could use the -x debug shell option in the test scripts, rerun the 
failing ones and they will show why these test cases exactly fail.

If you find the reason for the unexpected failures then the btrfs result 
will be quite good. Apparently it has only a few link, truncate, and unlink 
ctimes update problems. I think that's quite impressive in its state of 
development.
