In nvmet_check_ctrl_status() cmd can be derived from nvmet_req. Remove
the local variable cmd in the nvmet_check_ctrl_status() and function
parameter cmd for nvmet_check_ctrl_status(). Derive the cmd value from
req parameter in the nvmet_check_ctrl_status().

In the function nvmet_alloc_ctrl() we assign status value before we
call nvmet_fine_get_subsys() to:
status = NVME_SC_CONNECT_INVALID_PARAM | NVME_SC_DNR;
After we successfully find the subsystem we again set the status value
to:
status = NVME_SC_CONNECT_INVALID_PARAM | NVME_SC_DNR;
Remove the duplicate status assignment value.

The barriers were added to the nvme_irq() in commit 3a7afd8ee42a
("nvme-pci: remove the CQ lock for interrupt driven queues") to prevent
compiler from doing memory optimization for the variabes that were
protected previously by spinlock in nvme_irq() at completion queue
processing and with queue head check condition.
The variable nvmeq->last_cq_head from those checks was removed in the
commit f6c4d97b0d82 ("nvme/pci: Remove last_cq_head") that was not
allwing poll queues from mistakenly triggering the spurious interrupt
detection.
Remove the barriers which were protecting the updates to the variables.

Reading /proc/mdstat with a read buffer size that would not
fit the unused status line in the first read will skip this
line from the output.
So 'dd if=/proc/mdstat bs=64 2>/dev/null' will not print something
like: unused devices: <none>
Don't return NULL immediately in start() for v=2 but call
show() once to print the status line also for multiple reads.

For far layout, the discard region is not continuous on disks. So it needs
far copies r10bio to cover all regions. It needs a way to know all r10bios
have finish or not. Similar with raid10_sync_request, only the first r10bio
master_bio records the discard bio. Other r10bios master_bio record the
first r10bio. The first r10bio can finish after other r10bios finish and
then return the discard bio.

Now the discard request is split by chunk size. So it takes a long time
to finish mkfs on disks which support discard function. This patch improve
handling raid10 discard request. It uses the similar way with patch
29efc390b (md/md0: optimize raid0 discard handling).
But it's a little complex than raid0. Because raid10 has different layout.
If raid10 is offset layout and the discard request is smaller than stripe
size. There are some holes when we submit discard bio to underlayer disks.
For example: five disks (disk1 - disk5)
D01 D02 D03 D04 D05
D05 D01 D02 D03 D04
D06 D07 D08 D09 D10
D10 D06 D07 D08 D09
The discard bio just wants to discard from D03 to D10. For disk3, there is
a hole between D03 and D08. For disk4, there is a hole between D04 and D09.
D03 is a chunk, raid10_write_request can handle one chunk perfectly. So
the part that is not aligned with stripe size is still handled by
raid10_write_request.
If reshape is running when discard bio comes and the discard bio spans the
reshape position, raid10_write_request is responsible to handle this
discard bio.
I did a test with this patch set.

"Fix an oversight in the handling of EFI_RT_PROPERTIES_TABLE, which was

into account"
* tag 'efi-urgent-for-v5.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:

The EFI_RT_PROPERTIES_TABLE contains a mask of runtime services that are
available after ExitBootServices(). This mostly does not concern the EFI
stub at all, given that it runs before that. However, there is one call
that is made at runtime, which is the call to SetVirtualAddressMap()
(which is not even callable at boot time to begin with)
So add the missing handling of the RT_PROP table to ensure that we only
call SetVirtualAddressMap() if it is not being advertised as unsupported
by the firmware.

commit 0d8359620d9b ("zram: support page writeback") introduced two
problems. It overwrites writeback_store's return value as kstrtol's
return value, which makes return value zero so user could see zero as
return value of write syscall even though it wrote data successfully.
It also breaks index value in the loop in that it doesn't increase the
index any longer. It means it can write only first starting block index
so user couldn't write all idle pages in the zram so lose memory saving
chance.
This patch fixes those issues.

writeback_store's return value is overwritten by submit_bio_wait's return
value. Thus, writeback_store will return zero since there was no IO
error. In the end, write syscall from userspace will see the zero as
return value, which could make the process stall to keep trying the write
until it will succeed.

when user uses virtual addresses to access dram through debugfs,
driver translate this address to physical and use it
for the access through the pcie bar.
in case dram page size is different than the dmmu
page size, we need to have special treatment
for adding the page offset to the actual address, which
is to use the dram page size mask to fetch the page offset
from the virtual address, instead of the dmmu last hop shift.

A device can be removed from the PCI subsystem while a process holds the
file descriptor opened.
In such a case, the driver attempts to kill the process, but as it is
still possible that the process will be alive after this step, the
device removal will complete, and we will end up with a process object
that points to a device object which was already released.
To prevent the usage of this released device object, disable the
following file operations for this process object, and avoid the cleanup
steps when the file descriptor is eventually closed.
The latter is just a best effort, as memory leak will occur.

The refcount of the "hl_fpriv" structure is not used for the control
device, and thus hl_hpriv_put() is not called when releasing this
device.
This results with no call to put_pid(), so add it explicitly in
hl_device_release_ctrl().

The dentry for the created debugfs file was being saved, but never used
anywhere. As the pointer isn't needed for anything, and the debugfs
files are being properly removed by removing the parent directory,
remove the saved pointer as well, saving a tiny bit of memory and logic.

The pcl726 driver has an "interrupt" subdevice that supports Comedi
asynchronous commands, placing a value in the Comedi buffer for each
interrupt. The subdevice uses Comedi's 16-bit sample format but the
interrupt handler is calling `comedi_buf_write_samples()` with the
address of a 32-bit integer `&s->state`. On bigendian machines, this
will copy 2 bytes from the wrong end of the 32-bit integer. This isn't
really a problem since `s->state` will always be 0 for this subdevice,
but clean it up by using a 16-bit variable initialized to 0 to pass the
value.
