This patch implements the reservation feature, including:
1. reservation register(register, unregister and replace).
2. reservation acquire(acquire, preempt, preempt and abort).
3. reservation release(release and clear).
4. reservation report.
5. set feature and get feature of reservation notify mask.
6. get log page of reservation event.
Not supported:
1. persistent reservation through power loss.
Test cases:
Use nvme-cli and fio to test all implemented sub features:
1. use nvme resv-register to register host a registrant or
unregister or replace a new key.
2. use nvme resv-acquire to set host to the holder, and use fio
to send read and write io in all reservation type. And also
test preempt and "preempt and abort".
3. use nvme resv-report to show all registrants and reservation
status.
4. use nvme resv-release to release all registrants.
5. use nvme get-log to get events generated by the preceding
operations.
In addition, make reservation configurable, one can set ns to
support reservation before enable ns. The default of resv_enable
is false.

max_zone_append_sectors differs from all other queue limits in that the
final value used is not stored in the queue_limits but needs to be
obtained using queue_limits_max_zone_append_sectors helper. This not
only adds (tiny) extra overhead to the I/O path, but also can be easily
forgotten in file system code.
Add a new max_hw_zone_append_sectors value to queue_limits which is
set by the driver, and calculate max_zone_append_sectors from that and
the other inputs in blk_validate_zoned_limits, similar to how
max_sectors is calculated to fix this.

The commit 4c39529663b9 adds a warning about duplicate cache names if

The commit 4c39529663b9 adds a warning about duplicate cache names if
CONFIG_DEBUG_VM is selected. These warnings are triggered by the dm-bufio
code. The dm-bufio code allocates a slab cache with each client. It is
not possible to preallocate the caches in the module init function
because the size of auxiliary per-buffer data is not known at this point.
So, this commit changes dm-bufio so that it appends a unique atomic value
to the cache name, to avoid the warnings.

In ublk_ch_mmap(), queue id is calculated in the following way:
(vma->vm_pgoff << PAGE_SHIFT) / `max_cmd_buf_size`
'max_cmd_buf_size' is equal to
`UBLK_MAX_QUEUE_DEPTH * sizeof(struct ublksrv_io_desc)`
and UBLK_MAX_QUEUE_DEPTH is 4096 and part of UAPI, so 'max_cmd_buf_size'
is always page aligned in 4K page size kernel. However, it isn't true in
64K page size kernel.
Fixes the issue by always rounding up 'max_cmd_buf_size' with PAGE_SIZE.

Notice that hybrid_init_cpu_capacity_scaling() only needs to hold
hybrid_capacity_lock around __hybrid_init_cpu_capacity_scaling()
calls, so introduce a "locked" wrapper around the latter and call
it from the former. This allows to drop a local variable and a
label that are not needed any more.
Also, rename __hybrid_init_cpu_capacity_scaling() to
__hybrid_refresh_cpu_capacity_scaling() for consistency.
Interestingly enough, this fixes a locking issue introduced by commit
929ebc93ccaa ("cpufreq: intel_pstate: Set asymmetric CPU capacity on
hybrid systems") that put an arch_enable_hybrid_capacity_scale() call
under hybrid_capacity_lock, which was a mistake because the latter is
acquired in CPU hotplug paths and so it cannot be held around
cpus_read_lock() calls.

Add support for LTC7841. The LTC7841 is a high performance
PolyPhase® single output synchronous boost converter controller.
Multiphase operation reduces input and output capacitor
requirements and allows the use of smaller inductors than the
single-phase equivalent.
The relevant registers in the LTC7841 are similar to the
LTC7880, only reduced by some amount. So it's just a matter of adding
the chip id. The device also doesn't support polling, on top of the
reduced register set, so a separate case for setting the chip info is
added.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/hwmonto use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.
While touching these files, make indention of the struct initializer
consistent in several files.

Add support for manipulating the internal heater of sht4x devices.
Enabling the heater removes condensed water from the sensor surface
which disturbs the relative humidity measurements.
The heater can operate at three heating levels (20, 110 or 200
milliwatts). Also, two heating durations may be selected (0.1 or 1s).
Once the heating time elapses the heater is automatically switched off.
Changes since v3:
* struct sht4x_data: add heating_complete timestamp
* struct sht4x_data: add data_pending flag
* heater_enable_store: return -EINVAL if input != 1
* heater_enable_store: check for data->heating_complete and update it
* heater_enable_store: set data_pending flag after heating request
* sht4x_read_values: msleep if heating in progress
* sht4x_read_values: dont send measurement request if data_pending
* heater_enable attr: make it RW
* Documentation: update info about heater_enable attr
Changes since v2:
* heater_enable_store: remove unnecessary if
* Documentation: remove incorrect info about turning off the heater
* be more specific in the patch description
Changes since v1:
* explain the use case of the new attributes set
* heater_enable attr: make it write-only
* heater_enable_store: define cmd as u8 instead of u8*
* heater_enable_store: remove unreachable data path
* heater_enable_store: remove unnecessary lock
* heater_enable_store: call i2c_master_send only if status==true
* define attributes as DEVICE_ATTR_* instead of SENSOR_DEVICE_ATTR_*

INA260 is similar to other chips of the series, except it has an internal
shunt resistor. The calibration register is therefore not present. Also,
the current register address was changed, though that does not matter for
the driver since the shunt voltage register (which is now the current
register) value is already used to read the current.

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
While touching these structs, also remove commas after the sentinel
entries and use a consistent indention style.

The adf_init_aer() won't destroy device_reset_wq when alloc_workqueue()
for device_sriov_wq failed. Add destroy_workqueue for device_reset_wq to
fix this issue.

In case of an early failure in dasd_init, dasd_proc_init is never
called and /proc/dasd* files are never created. That can happen, for
example, if an incompatible or incorrect argument is provided to the
dasd_mod.dasd= kernel parameter.
However, the attempted removal of /proc/dasd* files causes 8 warnings
and backtraces in this case. 4 on the error path within dasd_init and
4 when the dasd module is unloaded. Notice the "removing permanent
/proc entry 'devices'" message that is caused by the dasd_proc_exit
function trying to remove /proc/devices instead of /proc/dasd/devices
since dasd_proc_root_entry is NULL and /proc/devices is indeed
permanent. Example:

While the cause is a user failure, the dasd module should handle the
situation more gracefully. One of the simplest solutions is to make
removal of the /proc/dasd* entries idempotent.
