Yes, I already have, a couple of hours before you sent this:
http://www.spinics.net/lists/linux-fsdevel/msg47357.html
We haven't found the root cause of the problem, and writeback cannot
hold off grab_super_passive() because writeback only holds read
locks on s_umount, just like grab_super_passive. So if
grab_super_passive is failing, there is some other, not yet
unidentified actor causing this problem....
Cheers,
Dave.
