OK.  Btrfs often behaves differently from ext4, exhibiting issues in
various places.

The above test uses uses readdir(2) and friends to test glob patterns,
so this could be an area where Btrfs yields different results.

But anyway, you said /tmp is not on Btrfs.

I’m not sure what could happen here.  Could you try to analyze the test
log and see what exactly is failing?  Once you’ve done that, you could
try to strace the test on both the “good” and the “bad” file system, to
spot the difference.

Alternately, you could leave that for upstream to solve.  ;-)

Thanks,
