[dm-devel] [dm-5.19 PATCH 14/21] dm: pass dm_io instance to dm_io_acct directly

[Mike Snitzer <snitzer@kernel.org>]

[-- Attachment #1: Type: application/octet-stream, Size: 1689 bytes --]

From: Ming Lei <ming.lei@redhat.com>

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