You might also try to replace it with

BUG_ON(!mutex_is_locked(&dentry->d_parent->d_inode->i_mutex))

ie add that "d_parent" there. Just for testing - I think the real fix
really is to remove it, but I'd personally be happier knowing that
_if_ it were to have that d_parent there, it would have worked.

It would also be interesting to hear if that name length could
possibly ever change, and we'd hit that test too. It looks like the
original code actually checked that the length was the same before
doing the overwrite.

ncpfs doesn't seem to be very actively maintained, I suspect Petr
isn't really using it any more.
