Subject: [PATCH 09/15] gfs2: merge gfs2_writeback_aops and gfs2_ordered_aops
Date: Mon,  1 Jul 2019 23:54:33 +0200	[thread overview]
Message-ID: <20190701215439.19162-10-hch@lst.de> (raw)
In-Reply-To: <20190701215439.19162-1-hch@lst.de>

The only difference between the two is that gfs2_ordered_aops sets the
set_page_dirty method to __set_page_dirty_buffers, but given that
__set_page_dirty_buffers is the default if no method is set there is
no need to to do that.  Merge the two sets of operations into one.
