Subject: no buffers in ext4_writepage?
Date: Tue, 15 Jun 2010 12:29:57 -0400 [thread overview]
Message-ID: <20100615162957.GA14500@infradead.org> (raw)
ext4_writepage currently has a and else case after the
page_has_buffers() check where it does I/O if there are no buffers
attached. But given how ext4 uses a write_begin method that always
creates buffer, the normal set_page_dirty which creates buffers
and a ->page_mkwrite that creates buffers I just can't see how that case
can happen at all.
