f5ebe7bb87 LICENSES update for 6.16-rc1 
Here is a single patch to the LICENSES/ directory to add the CC0 license
 that is currently used in the kcpuid x86 tool for one of their files.
 This fixes the error that spdxcheck.py currently has with the kcpuid
 file due to a missing LICENSE file for this specific license.
 
 This change has been in linux-next for weeks with no reported issues.

1a576136f8 drm/ttm: Fix compile error when CONFIG_SHMEM is not set 
When CONFIG_SHMEM is not set, the following compiler error occurs:

  ld: vmlinux.o: in function `ttm_backup_backup_page':
  (.text+0x10363bc): undefined reference to `shmem_writeout'
  make[3]: *** [/work/build/trace/nobackup/linux.git/scripts/Makefile.vmlinux:91: vmlinux.unstripped] Error 1

This is due to the replacement of writepage and calling swap_writeout()
and shmem_writeout() directly.  The issue is that when CONFIG_SHMEM is
not defined, shmem_writeout() is also not defined.

The function ttm_backup_backup_page() called mapping->a_ops->writepage()
which was then changed to call shmem_writeout() directly.

Even before commit 84798514db ("mm: Remove swap_writepage() and
shmem_writepage()"), it didn't make sense to call anything other than
shmem_writeout() as the ttm_backup deals only with shmem folios.

Have DRM_TTM config option select SHMEM to guarantee that
shmem_writeout() is available.

70087d2200 tracing fixes: 
- Fix UAF in module unload in ftrace when there's a bug in the module
 
   If a module is buggy and triggers ftrace_disable which is set when
   an anomaly is detected, when it gets unloaded it doesn't free
   the hooks into kallsyms, and when a kallsyms lookup is performed

   When a trace event or tracepoint is created but not used, it still

   not used: https://lore.kernel.org/linux-trace-kernel/20250529130138.544ffec4@gandalf.local.home/
 
   Remove the trace events that are created but not used. This does not
   remove trace events that are created but are not used due configs
   not being set. That will be handled later. This only removes events
   that have no user under any config.

Pull tracing fixes from Steven Rostedt:

 - Fix UAF in module unload in ftrace when there's a bug in the module

   If a module is buggy and triggers ftrace_disable which is set when an
   anomaly is detected, when it gets unloaded it doesn't free the hooks
   into kallsyms, and when a kallsyms lookup is performed it may access
   the mod->modname field and crash via UAF.

   Fix this by still freeing the mod_maps that are attached to kallsyms
   on module unload regardless if ftrace_disable is set or not.

a4a45a9a72 fsdax: Remove unused trace events for dax insert mapping 
When the dax_fault_actor() helper was factored out, it removed the calls
to the dax_pmd_insert_mapping and dax_insert_mapping events but never
removed the events themselves. As each event created takes up memory
(roughly 5K each), this is a waste as it is never used.

Remove the unused dax_pmd_insert_mapping and dax_insert_mapping trace
events.

   * Device Property API:
     * Split `device_get_child_node_count()` into a new helper `fwnode_get_child_node_count()` that
       doesn't require a device struct, making the API more symmetrical
   * Driver Modernization (using `fwnode_get_child_node_count()`):
     * Update `leds-pwm-multicolor`, `leds-ncp5623` and `leds-ncp5623` to use the new
       `fwnode_get_child_node_count()` helper, removing their custom implementation
     * As above in the USB Type-C TCPM driver

     * Remove default register definitions that are unused when regmap caching is not active
     * Use `devm_regulator_get_enable_optional()` to handle the optional regulator, simplifying
       enabling and removing manual disabling
     * Refactor `lp8860_unlock_eeprom()` to only perform the unlock operation, removing the lock
       part and an unnecessary parameter
     * Use a `devm` action to disable the enable-GPIO, simplifying cleanup and error paths, and
       remove the now-empty `.remove()` function
   * Turris Omnia LEDs:
     * Drop unnecessary commas in terminator entries of `struct attribute` and
       `struct of_device_id` arrays
   * MT6370 RGB LEDs:

     on-stack flexible structure definition with a utility function call

  Multicolor LEDs:
   - Fix issue where setting multi_intensity while software blinking is
     active could stop blinking

  PCA955x LEDs:
   - Avoid potential buffer overflow when creating default labels by
     changing a field's type to 'u8' and updating format specifiers

  PCA995x LEDs:
   - Fix a typo (stray space) in an 'of_device_id' entry in the
     'pca995x_of_match' table

  Kconfig:
   - Prevent LED drivers from being enabled by default when
     'COMPILE_TEST' is set

  Device Property API:
   - Split 'device_get_child_node_count()' into a new helper
     'fwnode_get_child_node_count()' that doesn't require a device
     struct, making the API more symmetrical

  Driver Modernization (using 'fwnode_get_child_node_count()'):
   - Update 'leds-pwm-multicolor', 'leds-ncp5623' and 'leds-ncp5623' to
     use the new 'fwnode_get_child_node_count()' helper, removing their
     custom implementation
   - As above in the USB Type-C TCPM driver

  Driver Modernization (using new GPIO setter callbacks):
   - Convert 'leds-lgm-sso' to use new GPIO line value setter callbacks
     which return an integer for error handling
   - Convert 'leds-pca955x', 'leds-pca9532' and 'leds-tca6507' to use
     new GPIO setter callbacks

  Documentation:
   - Remove the '.rst' extension for 'leds-st1202' in the documentation
     index for consistency

  LP8860 LEDs:
   - Use 'regmap_multi_reg_write()' for EEPROM writes instead of manual
     looping
   - Use scoped mutex guards and 'devm_mutex_init()' to simplify
     function exits and ensure automatic cleanup
   - Remove default register definitions that are unused when regmap
     caching is not active
   - Use 'devm_regulator_get_enable_optional()' to handle the optional
     regulator, simplifying enabling and removing manual disabling
   - Refactor 'lp8860_unlock_eeprom()' to only perform the unlock
     operation, removing the lock part and an unnecessary parameter
   - Use a 'devm' action to disable the enable-GPIO, simplifying cleanup
     and error paths, and remove the now-empty '.remove()' function

  Turris Omnia LEDs:
   - Drop unnecessary commas in terminator entries of 'struct attribute'
     and 'struct of_device_id' arrays

  MT6370 RGB LEDs:
   - Use the 'LINEAR_RANGE()' for defining 'struct linear_range' entries
     to improve robustness

  Texas Instruments TPS6131x:
   - Add new devicetree bindings for the TI TPS61310/TPS61311 flash LED
     driver"

9f2f6316d7 dm-stripe: small code cleanup 
This commit doesn't fix any bug, it is just code cleanup. Use the
function format_dev_t instead of sprintf, because format_dev_t does the
same thing.

Remove the useless memset call.

An unsigned integer can take at most 10 digits, so extend the array size
to 22. (note that because the range of minor and major numbers is limited,
the size 16 could not be exceeded, thus this function couldn't write
beyond string end)

"use_fec_from_device", "root_hash_sig_key_desc" were specified more than
once on the target line, a memory leak would happen.

This commit fixes the memory leak. It also fixes error handling in
verity_verify_sig_parse_opt_args.

829451beae dm-mirror: fix a tiny race condition 
There's a tiny race condition in dm-mirror. The functions queue_bio and
write_callback grab a spinlock, add a bio to the list, drop the spinlock
and wake up the mirrord thread that processes bios in the list.

It may be possible that the mirrord thread processes the bio just after
spin_unlock_irqrestore is called, before wakeup_mirrord. This spurious
wake-up is normally harmless, however if the device mapper device is
unloaded just after the bio was processed, it may be possible that
wakeup_mirrord(ms) uses invalid "ms" pointer.

Fix this bug by moving wakeup_mirrord inside the spinlock.

c8be542408 Modules changes for 6.16-rc1 
- Make .static_call_sites in modules read-only after init
 
   The .static_call_sites sections in modules have been made read-only after
   init to avoid any (non-)accidental modifications, similarly to how they
   are read-only after init in vmlinux.
 
 - The rest are minor cleanups.
 
 The changes have been on linux-next for 2 months, with the exception of the
 last comment-only cleanup.
 
 As discussed previously, we rotate module maintainership among its
 co-maintainers every 6 months. Daniel Gomez is next in line and he will
 send the next pull request for the modules.

Merge tag 'fuse-update-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse

Pull fuse updates from Miklos Szeredi:

 - Remove tmp page copying in writeback path (Joanne).

   This removes ~300 lines and with that a lot of complexity related to
   avoiding reclaim related deadlock. The old mechanism is replaced with
   a mapping flag that tells the MM not to block reclaim waiting for
   writeback to complete. The MM parts have been reviewed/acked by
   respective maintainers.

 - Convert more code to handle large folios (Joanne). This still just
   adds the code to deal with large folios and does not enable them yet.

 - Allow invalidating all cached lookups atomically (Luis Henriques).
   This feature is useful for CernVMFS, which currently does this
   iteratively.

 - Align write prefaulting in fuse with generic one (Dave Hansen)

 - Fix race causing invalid data to be cached when setting attributes on
   different nodes of a distributed fs (Guang Yuan Wu)

 - Update documentation for passthrough (Chen Linxuan)

 - Add fdinfo about the device number associated with an opened
   /dev/fuse instance (Chen Linxuan)

 - Increase readdir buffer size (Miklos). This depends on a patch to VFS
   readdir code that was already merged through Christians tree.

b4f60a053a cifs: dns resolution is needed only for primary channel 
When calling cifs_reconnect, before the connection to the
server is reestablished, the code today does a DNS resolution and
updates server->dstaddr.

However, this is not necessary for secondary channels. Secondary
channels use the interface list returned by the server to decide
which address to connect to. And that happens after tcon is reconnected
and server interfaces are requested.

c184689399 cifs: update dstaddr whenever channel iface is updated 
When the server interface info changes (more common in clustered
servers like Azure Files), the per-channel iface gets updated.
However, this did not update the corresponding dstaddr. As a result
these channels will still connect (or try connecting) to older addresses.

1f396b9bfe cifs: reset connections for all channels when reconnect requested 
cifs_reconnect can be called with a flag to mark the session as needing
reconnect too. When this is done, we expect the connections of all
channels to be reconnected too, which is not happening today.

Without doing this, we have seen bad things happen when primary and
secondary channels are connected to different servers (in case of cloud
services like Azure Files SMB).

This change would force all connections to reconnect as well, not just
the sessions and tcons.

4c3b7df784 A big core MTD change is the introduction of a new class to always 
register a master device. This is a problem that has been there forever:
 the "master" device was not always present depending on a number of
 heuristics such as the presence of fixed partitions and the absence of a
 Kconfig symbol to force its presence. This was a problem for runtime PM
 operations which might not have the "master" device available in all
 situation.
 
 The SPI NAND subsystem has seen the introduction of DTR operations (the
 equivalent of DDR transfers), which involved quite a few preparation
 patches for clarifying macro names.
 
 In the raw NAND subsystem, the brcmnand driver has been "fixed" for old
 legacy SoCs with an update of the ->exec_op() hook, there has been the
 introduction of a new controller driver named Loongson-1, and the
 Qualcomm driver has received quite a few misc fixes as well as a new
 compatible.
 
 Finally, Macornix SPI NOR entries have been cleaned-up and some SFDP
 table fixups for Macronix MX25L3255E have been merged.
 
 Aside from this, there is the usual load of misc improvement, fixes,
 and yaml conversion.
