From c84b023a4c1461498abf0eda54f60e2fd64a1ca2 Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Sun, 24 Jun 2018 22:03:26 +0800 Subject: scsi: read host_busy via scsi_host_busy() No functional change. Just introduce scsi_host_busy() and replace the direct read of scsi_host->host_busy with this new API. Cc: Omar Sandoval , Cc: "Martin K.
