Subject: [PATCH AUTOSEL 4.19 39/57] scsi: core: Avoid that system resume triggers a kernel warning
Date: Fri, 29 Mar 2019 21:28:32 -0400	[thread overview]
Message-ID: <20190330012854.32212-39-sashal@kernel.org> (raw)
In-Reply-To: <20190330012854.32212-1-sashal@kernel.org>

From: Bart Van Assche <bvanassche@acm.org>

[ Upstream commit 388b4e6a00bb3097278ed1648ac5a1cb48c894e6 ]

scsi_device_quiesce() and scsi_device_resume() are called during
system-wide suspend and resume. scsi_device_quiesce() only succeeds for
SCSI devices that are in one of the RUNNING, OFFLINE or TRANSPORT_OFFLINE
states (see also scsi_set_device_state()).  This patch avoids that the
following warning is triggered when resuming a system for which quiescing a
SCSI device failed:

WARNING: CPU: 2 PID: 11303 at drivers/scsi/scsi_lib.c:2600 scsi_device_resume+0x4f/0x58
