SCSI misc on 20210902 

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.

What: /sys/class/scsi_device/*/device/hpb_param_sysfs/activation_thld
Date: February 2021
Contact: Avri Altman <avri.altman@wdc.com>
Description: In host control mode, reads are the major source of activation
trials. Once this threshold hs met, the region is added to the
"to-be-activated" list. Since we reset the read counter upon
write, this include sending a rb command updating the region
ppn as well.
What: /sys/class/scsi_device/*/device/hpb_param_sysfs/normalization_factor
Date: February 2021
Contact: Avri Altman <avri.altman@wdc.com>
Description: In host control mode, we think of the regions as "buckets".
Those buckets are being filled with reads, and emptied on write.
We use entries_per_srgn - the amount of blocks in a subregion as
our bucket size. This applies because HPB1.0 only handles
single-block reads. Once the bucket size is crossed, we trigger
a normalization work - not only to avoid overflow, but mainly
because we want to keep those counters normalized, as we are
using those reads as a comparative score, to make various decisions.
The normalization is dividing (shift right) the read counter by
the normalization_factor. If during consecutive normalizations
an active region has exhausted its reads - inactivate it.
What: /sys/class/scsi_device/*/device/hpb_param_sysfs/eviction_thld_enter
Date: February 2021
Contact: Avri Altman <avri.altman@wdc.com>
Description: Region deactivation is often due to the fact that eviction took
place: A region becomes active at the expense of another. This is
happening when the max-active-regions limit has been crossed.
In host mode, eviction is considered an extreme measure. We
want to verify that the entering region has enough reads, and
the exiting region has much fewer reads. eviction_thld_enter is
the min reads that a region must have in order to be considered
a candidate for evicting another region.
What: /sys/class/scsi_device/*/device/hpb_param_sysfs/eviction_thld_exit
Date: February 2021
Contact: Avri Altman <avri.altman@wdc.com>
Description: Same as above for the exiting region. A region is considered to
be a candidate for eviction only if it has fewer reads than
eviction_thld_exit.
What: /sys/class/scsi_device/*/device/hpb_param_sysfs/read_timeout_ms
Date: February 2021
Contact: Avri Altman <avri.altman@wdc.com>
Description: In order not to hang on to "cold" regions, we inactivate
a region that has no READ access for a predefined amount of
time - read_timeout_ms. If read_timeout_ms has expired, and the
region is dirty, it is less likely that we can make any use of
HPB reading it so we inactivate it. Still, deactivation has
its overhead, and we may still benefit from HPB reading this
region if it is clean - see read_timeout_expiries.
What: /sys/class/scsi_device/*/device/hpb_param_sysfs/read_timeout_expiries
Date: February 2021
Contact: Avri Altman <avri.altman@wdc.com>
Description: If the region read timeout has expired, but the region is clean,
just re-wind its timer for another spin. Do that as long as it
is clean and did not exhaust its read_timeout_expiries threshold.
What: /sys/class/scsi_device/*/device/hpb_param_sysfs/timeout_polling_interval_ms
Date: February 2021
Contact: Avri Altman <avri.altman@wdc.com>
Description: The frequency with which the delayed worker that checks the
read_timeouts is awakened.
What: /sys/class/scsi_device/*/device/hpb_param_sysfs/inflight_map_req
Date: February 2021
Contact: Avri Altman <avri.altman@wdc.com>
Description: In host control mode the host is the originator of map requests.
To avoid flooding the device with map requests, use a simple throttling
mechanism that limits the number of inflight map requests.

Saying Y here will enable generic SG (SCSI generic) v4 support
for any block device.
Unlike SG v3 (aka block/scsi_ioctl.c drivers/scsi/sg.c), SG v4
can handle complicated SCSI commands: tagged variable length cdbs
with bidirectional data transfers and generic request/response
protocols (e.g. Task Management Functions and SMP in Serial
Attached SCSI).
This option is required by recent UDEV versions to properly
access device serial numbers, etc.
If unsure, say Y.

/**
* sg_scsi_ioctl -- handle deprecated SCSI_IOCTL_SEND_COMMAND ioctl
* @q: request queue to send scsi commands down
* @disk: gendisk to operate on (option)
* @mode: mode used to open the file through which the ioctl has been
* submitted
* @sic: userspace structure describing the command to perform
*
* Send down the scsi command described by @sic to the device below
* the request queue @q. If @file is non-NULL it's used to perform
* fine-grained permission checks that allow users to send down
* non-destructive SCSI commands. If the caller has a struct gendisk
* available it should be passed in as @disk to allow the low level
* driver to use the information contained in it. A non-NULL @disk
* is only allowed if the caller knows that the low level driver doesn't
* need it (e.g. in the scsi subsystem).
*
* Notes:
* - This interface is deprecated - users should use the SG_IO
* interface instead, as this is a more flexible approach to
* performing SCSI commands on a device.
* - The SCSI command length is determined by examining the 1st byte
* of the given command. There is no way to override this.
* - Data transfers are limited to PAGE_SIZE
* - The length (x + y) must be at least OMAX_SB_LEN bytes long to
* accommodate the sense buffer when an error occurs.
* The sense buffer is truncated to OMAX_SB_LEN (16) bytes so that
* old code will not be surprised.
* - If a Unix error occurs (e.g. ENOMEM) then the user will receive
* a negative return and the Unix error code in 'errno'.
* If the SCSI command succeeds then 0 is returned.
* Positive numbers returned are the compacted SCSI error codes (4
* bytes in one int) where the lowest byte is the SCSI status.
