From 48d9b0d43105e0da2b7c135eedd24e51234fb5e4 Mon Sep 17 00:00:00 2001 From: Logan Gunthorpe Date: Thu, 10 Oct 2019 17:36:26 -0600 Subject: block: account statistics for passthrough requests Presently, passthrough requests are not accounted for because blk_do_io_stat() expressly rejects them. Based on some digging in the history, this doesn't seem like a concious decision but one that evolved from the change from blk_fs_request() to blk_rq_is_passthrough(). To support this, call blk_account_io_start() in blk_execute_rq_nowait() and remove the passthrough check in blk_do_io_stat().
