From 551eb598e5ea52996eb821f43740496a78a97b68 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Fri, 2 Jun 2017 14:21:53 -0700 Subject: scsi: Split scsi_internal_device_block() Instead of passing a "wait" argument to scsi_internal_device_block(), split this function into a function that waits and a function that doesn't wait. This will make it easier to serialize SCSI device state changes through a mutex.
