spi: hisi-kunpeng: Fixed the wrong debugfs node name in hisi_spi debugfs initialization
In hisi_spi_debugfs_init, spi controller pointer is calculated
by container_of macro, and the member is hs->dev. But the host
cannot be calculated offset directly by this. (hs->dev) points
to (pdev->dev), and it is the (host->dev.parent) rather than
(host->dev) points to the (pdev->dev), which is set in
__spi_alloc_controller.

In this patch, this issues is fixed by getting the spi_controller
data from pdev->dev by dev_get_drvdata() directly. (dev->driver_data)
points to the spi controller data in the probe stage.

spi: spi-sprd-adi: Fix double free in probe error path
The driver currently uses spi_alloc_host() to allocate the controller
but registers it using devm_spi_register_controller().

If devm_register_restart_handler() fails, the code jumps to the
put_ctlr label and calls spi_controller_put(). However, since the
controller was registered via a devm function, the device core will
automatically call spi_controller_put() again when the probe fails.
This results in a double-free of the spi_controller structure.

Fix this by switching to devm_spi_alloc_host() and removing the
manual spi_controller_put() call.

43f37d44f2 gpio: cadence: Add support for edge-triggered interrupts
The Cadence GPIO controller (CDNS IP6508) supports edge-triggered
interrupts (rising, falling, and both) via IRQ_TYPE, IRQ_VALUE,
and IRQ_ANY_EDGE registers. This commit enables support for these
modes in cdns_gpio_irq_set_type().

Although the interrupt status register is cleared on read and lacks
per-pin acknowledgment, the driver already handles this safely by
reading the ISR once and dispatching all pending interrupts immediately.
This allows edge IRQs to be used reliably in controlled environments.

On the Axiado AX3000 platform, pinmux and pin configuration (such as
direction and output enable) are configured by the hardware/firmware
at boot time before Linux boots.

To prevent conflicts, introduce a platform-specific quirk triggered by
the "axiado,ax3000-gpio" compatible string.

When this quirk is active, the driver will skip its default
initialization of pinmux configuration and direction settings during
probe.

378f1dc3d6 xen: privcmd: WQ_PERCPU added to alloc_workqueue users
Currently if a user enqueue a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistentcy cannot be addressed without refactoring the API.

alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.

This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.

This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:

commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")

This change adds a new WQ_PERCPU flag to explicitly request alloc_workqueue()
to be per-cpu when WQ_UNBOUND has not been specified.

With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.

Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.

Merge patch series "Fix vm.dirtytime_expire_seconds=0 causing 100% CPU"
Laveesh Bansal <laveeshb@laveeshbansal.com> says:

Setting vm.dirtytime_expire_seconds to 0 causes wakeup_dirtytime_writeback()
to reschedule itself with a delay of 0, creating an infinite busy loop that
spins kworker at 100% CPU.

This series:
- Patch 1: Fixes the bug by handling interval=0 as "disable writeback"
           (consistent with dirty_writeback_centisecs behavior)
- Patch 2: Documents that setting the value to 0 disables writeback

Tested by booting kernels in QEMU with virtme-ng:
- Buggy kernel: kworker CPU spikes to ~73% when interval set to 0
- Fixed kernel: CPU remains normal, writeback correctly disabled
- Re-enabling (0 -> non-zero): writeback resumes correctly

writeback: fix 100% CPU usage when dirtytime_expire_interval is 0
When vm.dirtytime_expire_seconds is set to 0, wakeup_dirtytime_writeback()
schedules delayed work with a delay of 0, causing immediate execution.
The function then reschedules itself with 0 delay again, creating an
infinite busy loop that causes 100% kworker CPU usage.

Fix by:
- Only scheduling delayed work in wakeup_dirtytime_writeback() when
  dirtytime_expire_interval is non-zero
- Cancelling the delayed work in dirtytime_interval_handler() when
  the interval is set to 0
- Adding a guard in start_dirtytime_writeback() for defensive coding

Tested by booting kernel in QEMU with virtme-ng:
- Before fix: kworker CPU spikes to ~73%
- After fix: CPU remains at normal levels
- Setting interval back to non-zero correctly resumes writeback

readdir: require opt-in for d_type flags
Commit c31f91c6af ("fuse: don't allow signals to interrupt getdents
copying") introduced the use of high bits in d_type as flags. However,
overlayfs was not adapted to handle this change.

In ovl_cache_entry_new(), the code checks if d_type == DT_CHR to
determine if an entry might be a whiteout. When fuse is used as the
lower layer and sets high bits in d_type, this comparison fails,
causing whiteout files to not be recognized properly and resulting in
incorrect overlayfs behavior.

Fix this by requiring callers of iterate_dir() to opt-in for getting
flag bits in d_type outside of S_DT_MASK.

Merge patch series "vfs: require filesystems to explicitly opt-in to lease support"
Jeff Layton <jlayton@kernel.org> says:

Yesterday, I sent patches to fix how directory delegation support is
handled on filesystems where the should be disabled [1]. That set is
appropriate for v6.19. For v7.0, I want to make lease support be more
opt-in, rather than opt-out:

For historical reasons, when ->setlease() file_operation is set to NULL,
the default is to use the kernel-internal lease implementation. This
means that if you want to disable them, you need to explicitly set the
->setlease() file_operation to simple_nosetlease() or the equivalent.

This has caused a number of problems over the years as some filesystems
have inadvertantly allowed leases to be acquired simply by having left
it set to NULL. It would be better if filesystems had to opt-in to lease
support, particularly with the advent of directory delegations.

This series has sets the ->setlease() operation in a pile of existing
local filesystems to generic_setlease() and then changes
kernel_setlease() to return -EINVAL when the setlease() operation is not
set.

With this change, new filesystems will need to explicitly set the
->setlease() operations in order to provide lease and delegation
support.

I mainly focused on filesystems that are NFS exportable, since NFS and
SMB are the main users of file leases, and they tend to end up exporting
the same filesystem types. Let me know if I've missed any.

fs: remove simple_nosetlease()
Setting ->setlease() to a NULL pointer now has the same effect as
setting it to simple_nosetlease(). Remove all of the setlease
file_operations that are set to simple_nosetlease, and the function
itself.

filelock: default to returning -EINVAL when ->setlease operation is NULL
Now that most filesystems where we expect to need lease support have
their ->setlease() operations explicitly set, change kernel_setlease()
to return -EINVAL when the setlease is a NULL pointer.

Also update the Documentation/ with info about this change.
