Subject: [PATCH v5.3 06/11] btrfs: extent_io: Kill the dead branch in extent_write_cache_pages()
Date: Wed, 20 Mar 2019 14:27:44 +0800 [thread overview]
Message-ID: <20190320062749.30953-7-wqu@suse.com> (raw)
In-Reply-To: <20190320062749.30953-1-wqu@suse.com>
Since __extent_writepage() will no longer return >0 value,
(ret == AOP_WRITEPAGE_ACTIVATE) will never be true.
Kill that dead branch.
