Subject: [dm-devel] [PATCH 3/8] dm: pass 'dm_io' instance to dm_io_acct directly
Date: Tue, 12 Apr 2022 16:56:11 +0800	[thread overview]
Message-ID: <20220412085616.1409626-4-ming.lei@redhat.com> (raw)
In-Reply-To: <20220412085616.1409626-1-ming.lei@redhat.com>

All the other 4 parameters are retrieved from the 'dm_io' instance, so
not necessary to pass all four to dm_io_acct().
