instead of TBROK:

Hi,
I suppose that EXDEV (in fanotify_test_fid()) is really error which
should be caught as TBROK (unlike ENODEV and EOPNOTSUPP). Am I correct?
Kind regards,
Petr

No. EXDEV is also an indication of problematic filesystem.
You will get it if you try to setup the mark on a btrfs subvolume, which is not
the root volume, because in that case the "fsid" information from event is
not reliable.
Probably this is not going to happen in LTP, but still.
Good spotting.
Thanks,
Amir.

Right, I'll add also check for EXDEV and merge with your Reviewed-by tag.
Thanks for your review!

Merged commit where handling both EOPNOTSUPP and EXDEV.
Thanks!
