My guess is that we're getting out early in xfs_setattr(), before the
DM_EVENT_ATTRIBUTE is generated.

At the end of xfs_setattr() you'll find a dm_send_namesp_event() and its
corresponding if-wrapper.  Put a copy of that if-block earlier in
xfs_setattr(), inside the "if (mask & AT_UPDTIMES)" conditional.

Let me know if that has anything to do with what you're seeing.
