Implementation
Use more preferable function name which implies using a pseudo-random
number generator.

Hi folks,
I have two LSI fusion / mpt2sas / mpt3sas device removal patches. These
changes were tested against 3.8.0, but still apply cleanly to scsi.git,
branch misc.
The first deletes pci_stop_and_remove_bus_device() calls from the three
drivers. I don't believe that this call is safe with
Device removal/addition is a PCI core function, not an HBA function.
Calling pci_stop_and_remove_bus_device() from a SCSI LLD may introduce
device removal races with PCI hotplug. Remove these calls from mptfusion,
mpt2sas, and mpt3sas, but leave remaining dead IOC code in place that
flushes
If a scsi host is removed during an asynchronous SCSI scan, the mpt2sas
and mpt3sas .scan_finished callback function may take up to 5 minutes to
timeout and notify the SCSI layer that the operation has failed. Once the
driver determines that an adapter is gone, stop waiting for the scan to
These changes were applied to scsi.git, branch misc. This patch
fixes a reference count bug in the SCSI tape driver which can be
reproduced with the following:
* Boot with slub_debug=FZPU, tape drive attached
* echo 1 /sys/devices/... tape device pci path .../remove
* Wait for device removal

I realized after I sent the last patch, that it was the wrong file (incorrectly
formatted) and missing the signature. That has been corrected in this version.
Other than that, the two patches are functionally identical.
This patch adds code to the lpfc driver to check the return status from the

scsilun_to_int() has an error which prevents it from generating
correct LUN numbers for 64bit values.
Also we should remove the misleading comment about portions of
the LUN being ignored; the initiator should treat the LUN as
an opaque value.
With the things I've been doing in st it was easier to reboot than unload/load
the st driver since it would likely cause an oops. I applied the patch and have
tested it and the st module unloads/reloads with no problems now.

In August 2010, Jens and Alan discussed about Runtime PM and the block

Add runtime pm helper functions:

If device is suspended or is suspending and the request is not a

Add a flag REQ_PM to identify the request is PM related, such requests

Remove scsi_autopm_* from sd open/release path and check_events path.
