Subject: [PATCH v4 0/3] SCSI: Fix issues between removing device and error handle
Date: Thu, 7 Mar 2024 22:43:08 +0800 [thread overview]
Message-ID: <20240307144311.73735-1-haowenchao2@huawei.com> (raw)
I am testing SCSI error handle with my previous scsi_debug error
injection patches, and found some issues when removing device and
error handler happened together.
These issues are triggered because devices in removing would be skipped
when calling shost_for_each_device().
The issues are found:
1. statistic info printed at beginning of scsi_error_handler is wrong
2. device reset is not triggered
V4:
- Remove the forth patch which fix IO hang when device removing
becaust the issue is fixed by commit '6df0e077d76bd (scsi: core:
Kick the requeue list after inserting when flushing)'
V3:
- Update patch description
- Update comments of functions added
V2:
- Fix IO hang by run all devices' queue after error handler
- Do not modify shost_for_each_device() directly but add a new
helper to iterate devices but do not skip devices in removing
