Pull SCSI updates from James Bottomley:
"This series consists of the usual driver updates (ufs, qla2xxx,
target, smartpqi, lpfc, mpt3sas).
The core change causing the most churn was replacing the command
request field request with a macro, allowing us to offset map to it
and remove the redundant field; the same was also done for the tag
field.
The most impactful change is the final removal of scsi_ioctl, which
has been deprecated for over a decade"

Pull driver core updates from Greg KH:
"Here is the big set of driver core patches for 5.15-rc1.
These do change a number of different things across different
subsystems, and because of that, there were 2 stable tags created that
might have already come into your tree from different pulls that did
the following
- changed the bus remove callback to return void
- sysfs iomem_get_mapping rework
Other than those two things, there's only a few small things in here:
- kernfs performance improvements for huge numbers of sysfs users at
once
- tiny api cleanups
- other minor changes
All of these have been in linux-next for a while with no reported
problems, other than the before-mentioned merge issue"

The caller of this function (parisc_driver_remove() in
arch/parisc/kernel/drivers.c) ignores the return value, so better don't
return any value at all to not wake wrong expectations in driver authors.
The only function that could return a non-zero value before was
ipmi_parisc_remove() which returns the return value of
ipmi_si_remove_by_dev(). Make this function return void, too, as for all
other callers the value is ignored, too.
Also fold in a small checkpatch fix for:
WARNING: Unnecessary space before function pointer arguments
+ void (*remove) (struct parisc_device *dev);

Samsung KLUFG8RHDA-B2D1 does not clear the unit attention condition if the

We found a hang, the steps to reproduce are as follows:
1. blocking device via scsi_device_set_state()
2. dd if=/dev/sda of=/mnt/t.log bs=1M count=10
3. echo none > /sys/block/sda/queue/scheduler
4. echo "running" >/sys/block/sda/device/state
Step 3 and 4 should complete after step 4, but they hang.

Complete the enablement of the cm framework feature in the adapter. Perform
the following:
- Detect the presence of the congestion management framework feature.
When the cm framework is present:
- Issue the SET_FEATURE command to enable the feature.
- Register the cm statistics buffer with the adapter.
- Read the cm enablement buffer to determine the cm framework state for cm
management.
When cm management is enabled:
- Monitor all FPIN and congestion signalling events, incrementing
counters.
- Regularly sync with the adapter to communicate congestion events and to
receive an rx request limit.
- Monitor requests for rx data and ensure that no more than the
adapter prescribed limit is issued on the link. If the limit is
exceeded, SCSI and/or NVMe traffic is temporarily suspended.
- Maintain the minute, hourly, daily statistics buffer.
- Monitor for congestion enablement change events, causing a reread of the
enablement buffer and acting on any change in enablement.
And:
- Add teardown logic, including buffer deregistration, on adapter
detachment or reset.

When congestion mgmt is enabled, cmf has the driver regularly issue a
command to synchronize reporting of congestion mgmt events such as fpin and
signal delivery.
This patch adds the definition of the CMF_SYNC WQE and its CQE fields as
well as support for issuing the command. The patch also adds the few
remaining cmf-related SLI additions, such as feature definition for
enablement of CMF and notifications to the driver if the cm enablement mode
changes.

As part of the cmf framework, the firmware maintains a table with
congestion related state information, specifically whether enabled and if
enabled, whether monitoring or actively managing congestion.

The cmf framework requires the driver to maintain a cm statistics table,
accessible inband, of congestion related statistics that are reported per
minute, rolled up to per hour, and rolled up again per day. Several days
worth may be maintained. The table is registered with the adapter when the
MIB feature is enabled.
Add definition of the table and add support to register the table with the
adapter. Includes definition and initialization of event counters that are
later added to the statistics table.

MIB support is currently limited to detecting support in the adapter and
ensuring FDMI support is enabled if present. For the new framework MIB
support also requires active enablement of support via the SET_FEATURES
command with the firmware.
Rework the MIB detection and enablement for the following:
- Move detection away from the get_sli4_parameters routine, and into the
hba_setup path. get_sli4_parameters is only called once at attachment
while hba_setup is called as part of any SLI port reset path. This
ensures detection after firmware download.
- Update SET_FEATURES mbx command for the MIB enablement feature and add
support for the feature.
- Create the cmf_setup routine to encapsulate the detection of MIB support
and perform the enablement of the MIB support feature.

When Target port transitions personality from one to another (NVMe <-->

while the other layer is coming up. This overlap can cause temporary I/O
error. Detect those errors/transitions and recover from them. Triggers
session tear down and allow relogin to re-drive the connection under the
following conditions:
- NVMe command error
- On PRLO + N2N (rida format 2)

For target port that register itself as both FCP + NVMe, initiator driver
will try to login one mode at a time. If the last mode did not succeed,
then driver will try the other mode.
When error is encountered, current code only flip to other mode one time
(NVMe->FCP) and remain on the last mode. Driver wrongly assumed target
port does not support PRLI NVMe, instead it was not ready to receive PRLI.
This patch will alternate back and forth on every PRLI failure until login
retry count has depleted or it is succeeded.
