Subject: [PATCH v3 2/4] scsi: scsi_error: Fix wrong statistic when print error info
Date: Mon, 16 Oct 2023 10:03:12 +0800	[thread overview]
Message-ID: <20231016020314.1269636-3-haowenchao2@huawei.com> (raw)
In-Reply-To: <20231016020314.1269636-1-haowenchao2@huawei.com>

shost_for_each_device() would skip devices which is in progress of
removing, so commands of these devices would be ignored in
scsi_eh_prt_fail_stats().

Fix this issue by using shost_for_each_device_include_deleted()
to iterate devices in scsi_eh_prt_fail_stats().
