Subject: [PATCH 5/6] btrfs: Always pass 0 bio_offset for btree_submit_bio_start
Date: Wed, 10 Apr 2019 17:24:42 +0300	[thread overview]
Message-ID: <20190410142443.6470-6-nborisov@suse.com> (raw)
In-Reply-To: <20190410142443.6470-1-nborisov@suse.com>

The btree submit hook queues the async csum and forwards the bio_offset
parameter passed to btree_submit_bio_hook. This is redundant since
btree_submit_bio_start calls btree_csum_one_bio which doesn't use
the offset at all. No functional changes.
