ext4: BUG_ON fix: check if page has buffers before calling page_buffers()
We need to make check if a page does not have buffes by checking
page_has_buffers(page) before calling page_buffers(page) in
ext4_writepage(). Otherwise page_buffers() could throw a BUG_ON.
Thanks also to Markus Trippelsdorf and Avinash Kurup who also reported
the problem.
