When Async scanning mode is enabled and device scanning is in progress,
devices should not be removed. But in actuality, devices are removed but
their transport layer entries are not removed. This causes error to add
the same device to the transport layer after host reset or diagnostic
reset.

The purpose of this InfiniBand SRP initiator patch series is as follows:
- Make the SRP initiator driver better suited for use in a H.A. setup.
Speed up failover by reducing the IB RC retry count and by notifying
multipathd faster about transport layer failures by adding
fast_io_fail_tmo
An SRP target is required to maintain a single connection between
initiator and target. This means that if the 'add_target' attribute
is used to create a second connection to a target that the first
connection will be logged out and that the SCSI error handler will
kick in. The SCSI error handler
Keep the rport data structure around after srp_remove_host() has
finished until cleanup of the IB transport layer has finished
completely. This is necessary because later patches use the rport
pointer inside the queuecommand callback. Without this patch
accessing the rport from inside a
Add the necessary functions in the SRP transport module to allow
an SRP initiator driver to implement transport layer error handling
similar to the functionality already provided by the FC transport
layer. This includes:
- Support for implementing fast_io_fail_tmo, the time that should
elapse

Avoid that path failover in a multipath setup causes the SCSI layer
to generate kernel messages about SCSI command failures. This patch
speeds up SRP initiator operation significantly when monitoring
kernel messages over a serial port.

The MN10300 arch is throwing up an error in the SCSI driver and I'm not sure
whether it needs fixing in the arch - in get_user() - or in the SCSI code.
The problem is this line in sg_scsi_ioctl():
if (get_user(opcode, sic-data))
sic points to the following struct:

This patch series replace the previous Query Request and NOP patches:
[PATCH 1/8] scsi: ufs: add support for query
[PATCH 6/8] scsi: ufs: Add support for sending NOP OUT UPIU
[PATCH 7/8] scsi: ufs: Set fDeviceInit flag to initiate device initialization
Major difference -
Sending the query
As part of device initialization sequence, sending NOP OUT UPIU and
waiting for NOP IN UPIU response is mandatory. This confirms that the
device UFS Transport (UTP) layer is functional and the host can configure
the device with further commands. Add support for sending NOP OUT UPIU to
check the

Allow UFS device to complete its initialization and accept
SCSI commands by setting fDeviceInit flag. The device may take
time for this operation and hence the host should poll until
fDeviceInit flag is toggled to zero. This step is mandated by

Add host assisted background operations for UFS device and runtime PM
helpers for ufshcd platform and pci glue drivers. The background operations
are disabled during runtime resume and enabled when the device is idle and
runtime suspended.
These patches depends on:

during runtime suspend/resume of the device.

Currently, sending Task Management (TM) command to the card might
be broken in some scenarios as listed below:
Problem: If there are more than 8 TM commands the implementation
returns error to the caller.
Fix: Wait for one of the slots to be emptied and send the command.
Problem:
As of now SCSI initiated error handling is broken because,
the reset APIs don't try to bring back the device initialized and
ready for further transfers.
In case of timeouts, the scsi error handler takes care of handling aborts
and resets. Improve the error handling in such scenario by resetting
