That would be a missing PagePrivate bit in page_buffers() called from
end_buffer_async_write.  PG_private can only be cleared via drop_buffers
which requires the page not having PG_writeback set which must be
set until end_buffer_async_write is done.  Very strange, and all this
is generic code without xfs involvement.  Did this happen once
or can you reproduce it?
