From e165fb4dd6985b37215178e514a2e09dab8fef14 Mon Sep 17 00:00:00 2001 From: Chaitanya Kulkarni Date: Mon, 27 Mar 2023 00:34:26 -0700 Subject: block: open code __blk_account_io_start() There is only one caller for __blk_account_io_start(), the function is small enough to fit in its caller blk_account_io_start(). Remove the function and opencode in the its caller blk_account_io_start().
