Subject: [PATCH 8/8] bcache: remove bch_crc64_update
Date: Wed, 20 Oct 2021 22:38:12 +0800 [thread overview]
Message-ID: <20211020143812.6403-9-colyli@suse.de> (raw)
In-Reply-To: <20211020143812.6403-1-colyli@suse.de>
From: Christoph Hellwig <hch@lst.de>
bch_crc64_update is an entirely pointless wrapper around crc64_be.
