Driver core fixes for 6.8-rc5
Here are some driver core fixes, a kobject fix, and a documentation
update for 6.8-rc5. In detail these changes are:
- devlink fixes for reported issues with 6.8-rc1
- topology scheduling regression fix that has been reported by many
- kobject loosening of checks change in -rc1 is now reverted as some
codepaths seemed to need the checks
- documentation update for the CVE process. Has been reviewed by
many, the last minute change to the document was to bring the .rst
format back into the the new style rules, the contents did not
change.
All of these, except for the documentation update, have been in
linux-next for over a week. The documentation update has been reviewed
for weeks by a group of developers, and in public for a week and the
wording has stabilized for now. If future changes are needed, we can do
so before 6.8-final is out (or anytime after that.)

Tracing fixes for v6.8:
- Fix the #ifndef that didn't have CONFIG_ on HAVE_DYNAMIC_FTRACE_WITH_REGS The fix to have dynamic trampolines work with x86 broke arm64 as the config used in the #ifdef was HAVE_DYNAMIC_FTRACE_WITH_REGS and not CONFIG_HAVE_DYNAMIC_FTRACE_WITH_REGS which removed the fix that the previous fix was to fix. - Fix tracing_on state The code to test if "tracing_on" is set used ring_buffer_record_is_on() which returns false if the ring buffer isn't able to be written to. But the ring buffer disable has several bits that disable it. One is internal disabling which is used for resizing and other modifications of the ring buffer. But the "tracing_on" user space visible flag should only report if tracing is actually on and not internally disabled, as this can cause confusion as writing "1" when it is disabled will not enable it. Instead use ring_buffer_record_is_set_on() which shows the user space visible settings. - Fix a false positive kmemleak on saved cmdlines Now that the saved_cmdlines structure is allocated via alloc_page() and not via kmalloc() it has become invisible to kmemleak. The allocation done to one of its pointers was flagged as a dangling allocation leak. Make kmemleak aware of this allocation and free. - Fix synthetic event dynamic strings.

kunit: device: Unregister the kunit_bus on shutdown
If KUnit is built as a module, and it's unloaded, the kunit_bus is not
unregistered. This causes an error if it's then re-loaded later, as we
try to re-register the bus.
Unregister the bus and root_device on shutdown, if it looks valid.
In addition, be more specific about the value of kunit_bus_device. It
is:
- a valid struct device* if the kunit_bus initialised correctly.
- an ERR_PTR if it failed to initialise.
- NULL before initialisation and after shutdown.

stackdepot: make fast paths lock-less again
With the introduction of the pool_rwlock (reader-writer lock), several
fast paths end up taking the pool_rwlock as readers. Furthermore,
stack_depot_put() unconditionally takes the pool_rwlock as a writer.
Despite allowing readers to make forward-progress concurrently,
reader-writer locks have inherent cache contention issues, which does not
scale well on systems with large CPU counts.
Rework the synchronization story of stack depot to again avoid taking any
locks in the fast paths. This is done by relying on RCU-protected list
traversal, and the NMI-safe subset of RCU to delay reuse of freed stack
records. See code comments for more details.
Along with the performance issues, this also fixes incorrect nesting of
rwlock within a raw_spinlock, given that stack depot should still be
usable from anywhere:
| [ BUG: Invalid wait context ]
| -----------------------------
| swapper/0/1 is trying to lock:
| ffffffff89869be8 (pool_rwlock){..--}-{3:3}, at: stack_depot_save_flags
| other info that might help us debug this:
| context-{5:5}
| 2 locks held by swapper/0/1:
| #0: ffffffff89632440 (rcu_read_lock){....}-{1:3}, at: __queue_work
| #1: ffff888100092018 (&pool->lock){-.-.}-{2:2}, at: __queue_work <-- raw_spin_lock
Stack depot usage stats are similar to the previous version after a KASAN
kernel boot:
$ cat /sys/kernel/debug/stackdepot/stats
pools: 838
allocations: 29865
frees: 6604
in_use: 23261
freelist_size: 1879
The number of pools is the same as previously. The freelist size is
minimally larger, but this may also be due to variance across system
boots. This shows that even though we do not eagerly wait for the next
RCU grace period (such as with synchronize_rcu() or call_rcu()) after
freeing a stack record - requiring depot_pop_free() to "poll" if an entry
may be used - new allocations are very likely to happen in later RCU grace
periods.

lib/Kconfig.debug: Update AS_HAS_NON_CONST_LEB128 comment and name
Fangrui noted that the comment around CONFIG_AS_HAS_NON_CONST_LEB128 could be made more accurate because explicit .sleb128 directives are not emitted, only .uleb128 directives are. Rename the symbol to CONFIG_AS_HAS_NON_CONST_ULEB128 as a result. Further clarifications include replacing "symbol deltas" with the more accurate "label differences", noting that this issue has been resolved in newer binutils (2.41+), and it only occurs when a port uses RISC-V style linker relaxation.

riscv: Restrict DWARF5 when building with LLVM to known working versions
LLVM prior to 18.0.0 would generate incorrect debug info for DWARF5 due to linker relaxation, which was worked around in clang by defaulting RISC-V to DWARF4 [1]. Unfortunately, this workaround does not work for the kernel because the DWARF version can be independently changed from the default in Kconfig. Do not allow DWARF5 to be selected for RISC-V when using linker relaxation (ld.lld >= 15.0.0) and a version of LLVM that does not have the fixes (the integrated assembler [2] and ld.lld [3] < 18.0.0) necessary to generate the correct debug info.

lib/Kconfig.debug: disable CONFIG_DEBUG_INFO_BTF for Hexagon
pahole, which generates BTF, relies on elfutils to process DWARF debug info. Because kernel modules are relocatable files, elfutils needs to resolve relocations when processing the DWARF .debug sections. Hexagon is not supported in binutils or elfutils, so elfutils is unable to process relocations in kernel modules, causing pahole to crash during BTF generation. Do not allow CONFIG_DEBUG_INFO_BTF to be selected for Hexagon until it is supported in elfutils, so that there are no more cryptic build failures during BTF generation.

Networking changes for 6.8.
Core & protocols
----------------
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up
build time warnings to safeguard against future header changes.
This improves TCP performances with many concurrent connections
up to 40%.
- Add page-pool netlink-based introspection, exposing the
memory usage and recycling stats. This helps indentify
bad PP users and possible leaks.
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set.
This lowers the time taken by connect() for hosts having
many active connections to the same destination.
- Refactor the TCP bind conflict code, shrinking related socket
structs.
- Refactor TCP SYN-Cookie handling, as a preparation step to
allow arbitrary SYN-Cookie processing via eBPF.
- Tune optmem_max for 0-copy usage, increasing the default value
to 128KB and namespecifying it.
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations.
- Reduce extension header parsing overhead at GRO time.
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries.
- Reorder nftables struct members, to keep data accessed by the
datapath first.
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer.
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex).
- More data-race annotations.
- Extend the diag interface to dump TCP bound-only sockets.
- Conditional notification of events for TC qdisc class and actions.
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID.
- Implement SMCv2.1 virtual ISM device support.
- Add support for Batman-avd mulicast packet type.
BPF
---
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers. It
improves the verifier "instructions processed" metric from single
digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload.
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y.
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques.
- Support uid/gid options when mounting bpffs.
- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is identified
by its id.
- Extend verifier to allow bpf_refcount_acquire() of a map value field
obtained via direct load which is a use-case needed in sched_ext.
- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter.
- Support for VLAN tag in XDP hints.
- Remove deprecated bpfilter kernel leftovers given the project
is developed in user-space (https://github.com/facebook/bpfilter).
Misc
----
- Support for parellel TC self-tests execution.
- Increase MPTCP self-tests coverage.
- Updated the bridge documentation, including several so-far
undocumented features.
- Convert all the net self-tests to run in unique netns, to
avoid random failures due to conflict and allow concurrent
runs.
- Add TCP-AO self-tests.
- Add kunit tests for both cfg80211 and mac80211.
- Autogenerate Netlink families documentation from YAML spec.
- Add yml-gen support for fixed headers and recursive nests, the
tool can now generate user-space code for all genetlink families
for which we have specs.
- A bunch of additional module descriptions fixes.
- Catch incorrect freeing of pages belonging to a page pool.
Driver API
----------
- Rust abstractions for network PHY drivers; do not cover yet the
full C API, but already allow implementing functional PHY drivers
in rust.
- Introduce queue and NAPI support in the netdev Netlink interface,
allowing complete access to the device <> NAPIs <> queues
relationship.
- Introduce notifications filtering for devlink to allow control
application scale to thousands of instances.
- Improve PHY validation, requesting rate matching information for
each ethtool link mode supported by both the PHY and host.
- Add support for ethtool symmetric-xor RSS hash.
- ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
platform.
- Expose pin fractional frequency offset value over new DPLL generic
netlink attribute.
- Convert older drivers to platform remove callback returning void.
- Add support for PHY package MMD read/write.

s390 updates for 6.8 merge window
- Add machine variable capacity information to /proc/sysinfo. - Limit the waste of page tables and always align vmalloc area size and base address on segment boundary. - Fix a memory leak when an attempt to register interruption sub class (ISC) for the adjunct-processor (AP) guest failed. - Reset response code AP_RESPONSE_INVALID_GISA to understandable by guest AP_RESPONSE_INVALID_ADDRESS in response to a failed interruption sub class (ISC) registration attempt. - Improve reaction to adjunct-processor (AP) AP_RESPONSE_OTHERWISE_CHANGED response code when enabling interrupts on behalf of a guest. - Fix incorrect sysfs 'status' attribute of adjunct-processor (AP) queue device bound to the vfio_ap device driver when the mediated device is attached to a guest, but the queue device is not passed through. - Rework struct ap_card to hold the whole adjunct-processor (AP) card hardware information. As result, all the ugly bit checks are replaced by simple evaluations of the required bit fields. - Improve handling of some weird scenarios between service element (SE) host and SE guest with adjunct-processor (AP) pass-through support. - Change local_ctl_set_bit() and local_ctl_clear_bit() so they return the previous value of the to be changed control register. This is useful if a bit is only changed temporarily and the previous content needs to be restored. - The kernel starts with machine checks disabled and is expected to enable it once trap_init() is called. However the implementation allows machine checks early. Consistently enable it in trap_init() only. - local_mcck_disable() and local_mcck_enable() assume that machine checks are always enabled. Instead implement and use local_mcck_save() and local_mcck_restore() to disable machine checks and restore the previous state. - Modification of floating point control (FPC) register of a traced process using ptrace interface may lead to corruption of the FPC register of the tracing process. Fix this. - kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point control (FPC) register in vCPU, but may lead to corruption of the FPC register of the host process. Fix this. - Use READ_ONCE() to read a vCPU floating point register value from the memory mapped area. This avoids that, depending on code generation, a different value is tested for validity than the one that is used. - Get rid of test_fp_ctl(), since it is quite subtle to use it correctly. Instead copy a new floating point control register value into its save area and test the validity of the new value when loading it. - Remove superfluous save_fpu_regs() call. - Remove s390 support for ARCH_WANTS_DYNAMIC_TASK_STRUCT. All machines provide the vector facility since many years and the need to make the task structure size dependent on the vector facility does not exist. - Remove the "novx" kernel command line option, as the vector code runs without any problems since many years. - Add the vector facility to the z13 architecture level set (ALS). All hypervisors support the vector facility since many years. This allows compile time optimizations of the kernel. - Get rid of MACHINE_HAS_VX and replace it with cpu_has_vx(). As result, the compiled code will have less runtime checks and less code. - Convert pgste_get_lock() and pgste_set_unlock() ASM inlines to C. - Convert the struct subchannel spinlock from pointer to member. -----BEGIN PGP SIGNATURE----- iI0EABYIADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCZZxnchccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8PyGAP9Z0Z1Pm3hPf24M4FgY5uuRqBHo VoiuohOZRGONwifnsgEAmN/3ba/7d/j0iMwpUdUFouiqtwTUihh15wYx1sH2IA8= =F6YD -----END PGP SIGNATURE----- Merge tag 's390-6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Alexander Gordeev: - Add machine variable capacity information to /proc/sysinfo. - Limit the waste of page tables and always align vmalloc area size and base address on segment boundary. - Fix a memory leak when an attempt to register interruption sub class (ISC) for the adjunct-processor (AP) guest failed. - Reset response code AP_RESPONSE_INVALID_GISA to understandable by guest AP_RESPONSE_INVALID_ADDRESS in response to a failed interruption sub class (ISC) registration attempt. - Improve reaction to adjunct-processor (AP) AP_RESPONSE_OTHERWISE_CHANGED response code when enabling interrupts on behalf of a guest. - Fix incorrect sysfs 'status' attribute of adjunct-processor (AP) queue device bound to the vfio_ap device driver when the mediated device is attached to a guest, but the queue device is not passed through. - Rework struct ap_card to hold the whole adjunct-processor (AP) card hardware information.

sysctl-6.8-rc1
To help make the move of sysctls out of kernel/sysctl.c not incur a size
penalty sysctl has been changed to allow us to not require the sentinel, the
final empty element on the sysctl array. Joel Granados has been doing all this
work. On the v6.6 kernel we got the major infrastructure changes required to
support this. For v6.7 we had all arch/ and drivers/ modified to remove
the sentinel. For v6.8-rc1 we get a few more updates for fs/ directory only.
The kernel/ directory is left but we'll save that for v6.9-rc1 as those patches
are still being reviewed. After that we then can expect also the removal of the
no longer needed check for procname == NULL.
Let us recap the purpose of this work:
- this helps reduce the overall build time size of the kernel and run time
memory consumed by the kernel by about ~64 bytes per array
- the extra 64-byte penalty is no longer inncurred now when we move sysctls
out from kernel/sysctl.c to their own files
Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to see further
work by Thomas Weißschuh with the constificatin of the struct ctl_table.
Due to Joel Granados's work, and to help bring in new blood, I have suggested
for him to become a maintainer and he's accepted. So for v6.9-rc1 I look forward
to seeing him sent you a pull request for further sysctl changes. This also
removes Iurii Zaikin as a maintainer as he has moved on to other projects and
has had no time to help at all.

header cleanups for 6.8
The goal is to get sched.h down to a type only header, so the main thing happening in this patchset is splitting out various _types.h headers and dependency fixups, as well as moving some things out of sched.h to better locations. This is prep work for the memory allocation profiling patchset which adds new sched.h interdepencencies. Testing - it's been in -next, and fixes from pretty much all architectures have percolated in - nothing major. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKnAFLkS8Qha+jvQrE6szbY3KbnYFAmWfBwwACgkQE6szbY3K bnZPwBAAmuRojXaeWxi01IPIOehSGDe68vw44PR9glEMZvxdnZuPOdvE4/+245/L bRKU2WBCjBUokUbV9msIShwRkFTZAmEMPNfPAAsFMA+VXeDYHKB+ZRdwTggNAQ+I SG6fZgh5m0HsewCDxU8oqVHkjVq4fXn0cy+aL6xLEd9gu67GoBzX2pDieS2Kvy6j jnyoKTxFwb+LTQgph0P4EIpq5I2umAsdLwdSR8EJ+8e9NiNvMo1pI00Lx/ntAnFZ JftWUJcMy3TQ5u1GkyfQN9y/yThX1bZK5GvmHS9SJ2Dkacaus5d+xaKCHtRuFS1I 7C6b8PsNgRczUMumBXus44HdlNfNs1yU3lvVxFvBIPE1qC9pYRHrkWIXXIocXLLC oxTEJ6B2G3BQZVQgLIA4fOaxMVhmvKffi/aEZLi9vN9VVosd1a6XNKI6KbyRnXFp GSs9qDqszhn5I3GYNlDNQTc/8UsRlhPFgS6nS0By6QnvxtGi9QkU2tBRBsXvqwCy cLoCYIhc2tvugHvld70dz26umiJ4rnmxGlobStNoigDvIKAIUt1UmIdr1so8P8eH xehnL9ZcOX6xnANDL0AqMFFHV6I58CJynhFdUoXfVQf/DWLGX48mpi9LVNsYBzsI CAwVOAQ0UjGrpdWmJ9ueY/ABYqg9vRjzaDEXQ+MhAYO55CLaVsg= =3tyT -----END PGP SIGNATURE----- Merge tag 'header_cleanup-2024-01-10' of https://evilpiepirate.org/git/bcachefs Pull header cleanups from Kent Overstreet: "The goal is to get sched.h down to a type only header, so the main thing happening in this patchset is splitting out various _types.h headers and dependency fixups, as well as moving some things out of sched.h to better locations.

linux_kselftest-kunit-6.8-rc1
This KUnit update for Linux 6.8-rc1 consists of:
- a new feature that adds APIs for managing devices introducing
a set of helper functions which allow devices (internally a
struct kunit_device) to be created and managed by KUnit.
These devices will be automatically unregistered on
test exit. These helpers can either use a user-provided
struct device_driver, or have one automatically created and
managed by KUnit. In both cases, the device lives on a new
kunit_bus.
- changes to switch drm/tests to use kunit devices
- several fixes and enhancements to attribute feature
- changes to reorganize deferred action function introducing
KUNIT_DEFINE_ACTION_WRAPPER
- new feature adds ability to run tests after boot using debugfs
- fixes and enhancements to string-stream-test:
- parse ERR_PTR in string_stream_destroy()
- unchecked dereference in bug fix in debugfs_print_results()
- handling errors from alloc_string_stream()
- NULL-dereference bug fix in kunit_init_suite()

Pull KUnit updates from Shuah Khan:
- a new feature that adds APIs for managing devices introducing a set
of helper functions which allow devices (internally a struct
kunit_device) to be created and managed by KUnit.
These devices will be automatically unregistered on test exit. These
helpers can either use a user-provided struct device_driver, or have
one automatically created and managed by KUnit. In both cases, the
device lives on a new kunit_bus.
- changes to switch drm/tests to use kunit devices
- several fixes and enhancements to attribute feature
- changes to reorganize deferred action function introducing
KUNIT_DEFINE_ACTION_WRAPPER
- new feature adds ability to run tests after boot using debugfs
- fixes and enhancements to string-stream-test:
- parse ERR_PTR in string_stream_destroy()
- unchecked dereference in bug fix in debugfs_print_results()
- handling errors from alloc_string_stream()
- NULL-dereference bug fix in kunit_init_suite()

Pull ACPI updates from Rafael Wysocki:
"From the new features standpoint, the most significant change here is
the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
device enumeration code that will allow MIPI cameras to be enumerated
through the platform firmware on systems using ACPI.
Also significant is the switch-over to threaded interrupt handlers for
the ACPI SCI and the dedicated EC interrupt (on systems where the
former is not used) which essentially allows all ACPI code to run with
local interrupts enabled. That should improve responsiveness
significantly on systems where multiple GPEs are enabled and the
handling of one SCI involves many I/O address space accesses which
previously had to be carried out in one go with disabled interrupts on
the local CPU.
Apart from the above, the ACPI thermal zone driver will use the
Thermal fast Sampling Period (_TFP) object if available, which should
allow temperature changes to be followed more accurately on some
systems, the ACPI Notify () handlers can run on all CPUs (not just on
CPU0), which should generally speed up the processing of events
signaled through the ACPI SCI, and the ACPI power button driver will
trigger wakeup key events via the input subsystem (on systems where it
is a system wakeup device)
In addition to that, there are the usual bunch of fixes and cleanups.
Specifics:
- Add CSI-2 and DisCo for Imaging support to the ACPI device
enumeration code (Sakari Ailus, Rafael J. Wysocki)
- Adjust the cpufreq thermal reduction algorithm in the ACPI
processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd

Merge tag 'slab-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab updates from Vlastimil Babka:
- SLUB: delayed freezing of CPU partial slabs (Chengming Zhou)
Freezing is an operation involving double_cmpxchg() that makes a slab
exclusive for a particular CPU. Chengming noticed that we use it also
in situations where we are not yet installing the slab as the CPU
slab, because freezing also indicates that the slab is not on the
shared list. This results in redundant freeze/unfreeze operation and
can be avoided by marking separately the shared list presence by
reusing the PG_workingset flag.
This approach neatly avoids the issues described in

Debugobject changes for v6.8:
- Make tracking object use more robust: it's not safe to access a
tracking object after releasing the hashbucket lock. Create a
persistent copy for debug printouts instead.

mm, treewide: introduce NR_PAGE_ORDERS
NR_PAGE_ORDERS defines the number of page orders supported by the page allocator, ranging from 0 to MAX_ORDER, MAX_ORDER + 1 in total. NR_PAGE_ORDERS assists in defining arrays of page orders and allows for more natural iteration over them.

Merge branches 'acpi-osl', 'acpi-bus' and 'acpi-tables'
Merge low-level ACPICA interface changes, an _SB-scope _OSC handshake update and a data-only ACPI tables parsing code update for 6.8-rc1: - Switch over ACPI to using a threaded interrupt handler for the SCI (Rafael J. Wysocki). - Allow ACPI Notify () handlers to run on all CPUs and clean up the ACPI interface for deferred events processing (Rafael J. Wysocki). - Switch over the ACPI EC driver to using a threaded handler for the dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki). - Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock to keep local interrupts on (Rafael J. Wysocki). - Adjust the USB4 _OSC handshake to correctly handle cases in which certain types of OS control are denied by the platform (Mika Westerberg). - Correct and clean up the generic function for parsing ACPI data-only tables with array structure (Yuntao Wang). * acpi-osl: ACPI: EC: Use a spin lock without disabing interrupts ACPI: EC: Use a threaded handler for dedicated IRQ ACPI: OSL: Use spin locks without disabling interrupts ACPI: OSL: Allow Notify () handlers to run on all CPUs ACPI: OSL: Rearrange workqueue selection in acpi_os_execute() ACPI: OSL: Rework error handling in acpi_os_execute() ACPI: OSL: Use a threaded interrupt handler for SCI * acpi-bus: ACPI: Run USB4 _OSC() first with query bit set * acpi-tables: ACPI: tables: Correct and clean up the logic of acpi_parse_entries_array() |

kunit: Fix some comments which were mistakenly kerneldoc
The KUnit device helpers are documented with kerneldoc in their header
file, but also have short comments over their implementation. These were
mistakenly formatted as kerneldoc comments, even though they're not
valid kerneldoc. It shouldn't cause any serious problems -- this file
isn't included in the docs -- but it could be confusing, and causes
warnings.
Remove the extra '*' so that these aren't treated as kerneldoc.

kunit: Add example of kunit_activate_static_stub() with pointer-to-function
Adds a variant of example_static_stub_test() that shows use of a pointer-to-function with kunit_activate_static_stub(). A const pointer to the add_one() function is declared. This pointer-to-function is passed to kunit_activate_static_stub() and kunit_deactivate_static_stub() instead of passing add_one directly.
