07d4cc2e74 kbuild: doc: Update default INSTALL_MOD_DIR from extra to updates
The default INSTALL_MOD_DIR was changed from 'extra' to
'updates' in commit b74d7bb7ca ("kbuild: Modify default
INSTALL_MOD_DIR from extra to updates").

This commit updates the documentation to align with the
latest kernel.

9cc5f3bf63 kbuild: Install dtb files as 0644 in Makefile.dtbinst
The compiled dtb files aren't executable, so install them with 0644 as their
permission mode, instead of defaulting to 0755 for the permission mode and
installing them with the executable bits set.

Some Linux distributions, including Debian, [1][2][3] already include fixes
in their kernel package build recipes to change the dtb file permissions to
0644 in their kernel packages.  These changes, when additionally propagated
into the long-term kernel versions, will allow such distributions to remove
their downstream fixes.

b8481381d4 perf tools fixes for v6.10: 2nd batch
- Update copies of kernel headers, which resulted in support for the new
   'mseal' syscall, SUBVOL statx return mask bit, RISC-V and PPC prctls,
   fcntl's DUPFD_QUERY, POSTED_MSI_NOTIFICATION IRQ vector, 'map_shadow_stack'
   syscall for x86-32.
 
 - Revert perf.data record memory allocation optimization that ended up
   causing a regression, work is being done to re-introduce it in the
   next merge window.
 
 - Fix handling of minimal vmlinux.h file used with BPF's CO-RE when
   interrupting the build.

771ed66105 One fix for the SiFive PRCI clocks so that the device boots again. This
driver was registering clkdev lookups that were always going to be
 useless. This wasn't a problem until clkdev started returning an error
 in these cases, causing this driver to fail probe, and thus boot to fail
 because clks are essential for most drivers. The fix is simple, don't
 use clkdev because this is a DT based system where clkdev isn't used.

   The private value holds pointer to our extent buffer structure

 - fix a crash, reported as duplicate key in metadata, but caused by a

0eafc58f21 HID: i2c-hid: elan: fix reset suspend current leakage
The Elan eKTH5015M touch controller found on the Lenovo ThinkPad X13s
shares the VCC33 supply with other peripherals that may remain powered
during suspend (e.g. when enabled as wakeup sources).

The reset line is also wired so that it can be left deasserted when the
supply is off.

This is important as it avoids holding the controller in reset for
extended periods of time when it remains powered, which can lead to
increased power consumption, and also avoids leaking current through the
X13s reset circuitry during suspend (and after driver unbind).

Use the new 'no-reset-on-power-off' devicetree property to determine
when reset needs to be asserted on power down.

Notably this also avoids wasting power on machine variants without a
touchscreen for which the driver would otherwise exit probe with reset
asserted.

e538d4b85b dt-bindings: HID: i2c-hid: elan: add 'no-reset-on-power-off' property
When the power supply is shared with other peripherals the reset line
can be wired in such a way that it can remain deasserted regardless of
whether the supply is on or not.

This is important as it can be used to avoid holding the controller in
reset for extended periods of time when it remains powered, something
which can lead to increased power consumption. Leaving reset deasserted
also avoids leaking current through the reset circuitry pull-up
resistors.

Add a new 'no-reset-on-power-off' devicetree property which can be used
by the OS to determine when reset needs to be asserted on power down.

Note that this property can also be used when the supply cannot be
turned off by the OS at all.

8d3ae46c64 dt-bindings: HID: i2c-hid: add dedicated Ilitek ILI2901 schema
The Ilitek ILI2901 touch screen controller was apparently incorrectly
added to the Elan eKTH6915 schema simply because it also has a reset
gpio and is currently managed by the Elan driver in Linux.

The two controllers are not related even if an unfortunate wording in
the commit message adding the Ilitek compatible made it sound like they
were.

Add a dedicated schema for the ILI2901 which does not specify the I2C
address (which is likely 0x41 rather than 0x10 as for other Ilitek touch
controllers) to avoid cluttering the Elan schema with unrelated devices
and to make it easier to find the correct schema when adding further
Ilitek controllers.

96c965667b kbuild: explicitly run mksysmap as sed script from link-vmlinux.sh
In commit b18b047002 ("kbuild: change scripts/mksysmap into sed
script"), the mksysmap script was transformed into a sed script,
made directly executable with "#!/bin/sed -f". Apparently, the path to
sed is different on NixOS.

The shebang can't use the env command, otherwise the "sed -f" command
would be treated as a single argument. This can be solved with the -S
flag, but that is a GNU extension. Explicitly use sed instead of relying
on the executable shebang to fix NixOS builds without breaking build
environments using Busybox.

f3a5367c67 btrfs: protect folio::private when attaching extent buffer folios
[BUG]
Since v6.8 there are rare kernel crashes reported by various people,
the common factor is bad page status error messages like this:

  BUG: Bad page state in process kswapd0  pfn:d6e840

  page dumped because: non-NULL mapping

[CAUSE]
Commit 09e6cef19c ("btrfs: refactor alloc_extent_buffer() to
allocate-then-attach method") changes the sequence when allocating a new
extent buffer.

Previously we always called grab_extent_buffer() under
mapping->i_private_lock, to ensure the safety on modification on
folio::private (which is a pointer to extent buffer for regular
sectorsize).

This can lead to the following race:

Thread A is trying to allocate an extent buffer at bytenr X, with 4
4K pages, meanwhile thread B is trying to release the page at X + 4K
(the second page of the extent buffer at X).

           Thread A                |                 Thread B
-----------------------------------+-------------------------------------
                                   | btree_release_folio()
				   | | This is for the page at X + 4K,
				   | | Not page X.
				   | |
alloc_extent_buffer()              | |- release_extent_buffer()
|- filemap_add_folio() for the     | |  |- atomic_dec_and_test(eb->refs)
|  page at bytenr X (the first     | |  |
|  page).                          | |  |
|  Which returned -EEXIST.         | |  |
|                                  | |  |
|- filemap_lock_folio()            | |  |
|  Returned the first page locked. | |  |
|                                  | |  |
|- grab_extent_buffer()            | |  |
|  |- atomic_inc_not_zero()        | |  |
|  |  Returned false               | |  |
|  |- folio_detach_private()       | |  |- folio_detach_private() for X
|     |- folio_test_private()      | |     |- folio_test_private()
      |  Returned true             | |     |  Returned true
      |- folio_put()               |       |- folio_put()

Now there are two puts on the same folio at folio X, leading to refcount
underflow of the folio X, and eventually causing the BUG_ON() on the
page->mapping.

The condition is not that easy to hit:

- The release must be triggered for the middle page of an eb
  If the release is on the same first page of an eb, page lock would kick
  in and prevent the race.

- folio_detach_private() has a very small race window
  It's only between folio_test_private() and folio_clear_private().

That's exactly when mapping->i_private_lock is used to prevent such race,
and commit 09e6cef19c ("btrfs: refactor alloc_extent_buffer() to
allocate-then-attach method") screwed that up.

At that time, I thought the page lock would kick in as
filemap_release_folio() also requires the page to be locked, but forgot
the filemap_release_folio() only locks one page, not all pages of an
extent buffer.

[FIX]
Move all the code requiring i_private_lock into
attach_eb_folio_to_filemap(), so that everything is done with proper
lock protection.

Furthermore to prevent future problems, add an extra
lockdep_assert_locked() to ensure we're holding the proper lock.

To reproducer that is able to hit the race (takes a few minutes with
instrumented code inserting delays to alloc_extent_buffer()):

  #!/bin/sh
  drop_caches () {
	  while(true); do
		  echo 3 > /proc/sys/vm/drop_caches
		  echo 1 > /proc/sys/vm/compact_memory
	  done
  }

  run_tar () {
	  while(true); do
		  for x in `seq 1 80` ; do
			  tar cf /dev/zero /mnt > /dev/null &
		  done
		  wait
	  done
  }

  mkfs.btrfs -f -d single -m single /dev/vda
  mount -o noatime /dev/vda /mnt
  # create 200,000 files, 1K each
  ./simoop -n 200000 -E -f 1k /mnt
  drop_caches &
  (run_tar)

Matthieu Baerts says:

====================
selftests: net: lib: small fixes

While looking at using 'lib.sh' for the MPTCP selftests [1], we found
some small issues with 'lib.sh'. Here they are:

- Patch 1: fix 'errexit' (set -e) support with busywait. 'errexit' is
  supported in some functions, not all. A fix for v6.8+.

- Patch 2: avoid confusing error messages linked to the cleaning part
  when the netns setup fails. A fix for v6.8+.

- Patch 3: set a variable as local to avoid accidentally changing the
  value of a another one with the same name on the caller side. A fix
  for v6.10-rc1+.
