From c12ea778654778f2039369323e8875e71d3a5609 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Mon, 29 Apr 2019 18:20:21 -0700 Subject: [PATCH] Linux 5.0 compat: Remove incorrect ASSERT Not all block devices, notably scsi_debug, set a root_blkg on the request queue. Remove this assertion and allow the the existing call to blkg_tryget() to gracefully handle the NULL (which it does).
