"Here is the large set of staging driver changes for 6.1-rc1.
Nothing really interesting in here at all except we deleted a driver
(fwserial) as no one had been using it for a long time. Other than
that, just the normal cleanups and minor fixes:
- rtl8723bs driver cleanups
- loads of r8188eu driver cleanups, making the driver smaller and
fixing up some firmware dependency issues.
- vt6655 driver cleanups.
- lots of other small staging driver cleanups.
All of these have been in linux-next for a while with no reported

NO_IRQ is used to check the return of irq_of_parse_and_map().
On some architecture NO_IRQ is 0, on other architectures it is -1.
irq_of_parse_and_map() returns 0 on error, independent of NO_IRQ.
So use 0 instead of using NO_IRQ.

A race condition may occur if the user physically removes the
USB device while calling open() for this device node.
This is a race condition between the ufx_ops_open() function and
the ufx_usb_disconnect() function, which may eventually result in UAF.
So, add a mutex to the ufx_ops_open() and ufx_usb_disconnect() functions
to avoid race contidion of krefs.

The log :
"genirq: Flags mismatch irq 0. 00000080 (virtio418) vs. 00015a00 (timer)"
was printed because of the irq 0 is used by timer exclusive,and when
vp_find_vqs call vp_find_vqs_msix and returns false twice (for
whatever reason), then it will call vp_find_vqs_intx as a fallback.
Because vp_dev->pci_dev->irq is zero, we request irq 0 with
flag IRQF_SHARED, and get a backtrace like above.
According to PCI spec about "Interrupt Pin" Register (Offset 3Dh):
"The Interrupt Pin register is a read-only register that identifies the
legacy interrupt Message(s) the Function uses. Valid values are 01h, 02h,
03h, and 04h that map to legacy interrupt Messages for INTA,
INTB, INTC, and INTD respectively. A value of 00h indicates that the
Function uses no legacy interrupt Message(s)."
So if vp_dev->pci_dev->pin is zero, we should not request legacy
interrupt.

Patch series "hugetlb: fixes for new vma lock series".
In review of the series "hugetlb: Use new vma lock for huge pmd sharing
synchronization", Miaohe Lin pointed out two key issues:
1) There is a race in the routine hugetlb_unmap_file_folio when locks
are dropped and reacquired in the correct order [1].
2) With the switch to using vma lock for fault/truncate synchronization,
we need to make sure lock exists for all VM_MAYSHARE vmas, not just
vmas capable of pmd sharing.
These two issues are addressed here. In addition, having a vma lock
present in all VM_MAYSHARE vmas, uncovered some issues around vma
splitting. Those are also addressed.
[1] https://lore.kernel.org/linux-mm/01f10195-7088-4462-6def-909549c75ef4@huawei.com/
This patch (of 3):
The hugetlb vma lock hangs off the vm_private_data field and is specific
to the vma. When vm_area_dup() is called as part of vma splitting, the
vma lock pointer is copied to the new vma. This will result in issues
such as double freeing of the structure. Update the hugetlb open vm_ops
to allocate a new vma lock for the new vma.
The routine __unmap_hugepage_range_final unconditionally unset VM_MAYSHARE
to prevent subsequent pmd sharing. hugetlb_vma_lock_free attempted to
anticipate this by checking both VM_MAYSHARE and VM_SHARED. However, if
only VM_MAYSHARE was set we would miss the free. With the introduction of
the vma lock, a vma can not participate in pmd sharing if vm_private_data
is NULL. Instead of clearing VM_MAYSHARE in __unmap_hugepage_range_final,
free the vma lock to prevent sharing. Also, update the sharing code to
make sure vma lock is indeed a condition for pmd sharing.
hugetlb_vma_lock_free can then key off VM_MAYSHARE and not miss any vmas.

wakeup_flusher_threads() was added under the assumption that if a system
runs out of clean cold pages, it might want to write back dirty pages more
aggressively so that they can become clean and be dropped.
However, doing so can breach the rate limit a system wants to impose on
writeback, resulting in early SSD wearout.

Pull SCSI updates from James Bottomley:
"Updates to the usual drivers (qla2xxx, lpfc, ufs, hisi_sas, mpi3mr,
mpt3sas, target). The biggest change (from my biased viewpoint) being
that the mpi3mr now attached to the SAS transport class, making it the
first fusion type device to do so.
Beyond the usual bug fixing and security class reworks, there aren't a
huge number of core changes"
