- Fix ref counter of buffers assigned at boot up
A tracing instance can be created from the kernel command line.
If it maps to memory, it is considered permanent and should not
be deleted, or bad things can happen. If it is not mapped to memory,
then the user is fine to delete it via rmdir from the instances
directory. But the ref counts assumed 0 was free to remove and
greater than zero was not. But this was not the case. When an
instance is created, it should have the reference of 1, and if
it should not be removed, it must be greater than 1. The boot up
code set normal instances with a ref count of 0, which could get
removed if something accessed it and then released it. And memory
mapped instances had a ref count of 1 which meant it could be deleted,
and bad things happen. Keep normal instances ref count as 1, and
set memory mapped instances ref count to 2.
- Protect sub buffer size (order) updates from other modifications
When a ring buffer is changing the size of its sub-buffers, no other
operations should be performed on the ring buffer. That includes
reading it. But the locking only grabbed the buffer->mutex that
keeps some operations from touching the ring buffer. It also must
hold the cpu_buffer->reader_lock as well when updates happen as
other paths use that to do some operations on the ring buffer.

A ring buffer which has its buffered mapped at boot up to fixed memory
should not be freed. Other buffers can be. The ref counting setup was
wrong for both. It made the not mapped buffers ref count have zero, and the
boot mapped buffer a ref count of 1. But an normally allocated buffer
should be 1, where it can be removed.
Keep the ref count of a normal boot buffer with its setup ref count (do
not decrement it), and increment the fixed memory boot mapped buffer's ref
count.

sysfs warns if we're removing a symlink from a directory that's no
longer in sysfs; this is triggered by fstests generic/730, which
simulates hot removal of a block device.
This patch is however not a correct fix, since checking
kobj->state_in_sysfs on a kobj owned by another subsystem is racy.
A better fix would be to add the appropriate check to
sysfs_remove_link() - and sysfs_create_link() as well.
But kobject_add_internal()/kobject_del() do not as of today have locking
that would support that.
Note that the block/holder.c code appears to be subject to this race as
well.

When creating a new stripe, we may reuse an existing stripe that has
some empty and some nonempty blocks.
Generally, the existing stripe won't change underneath us - except for
block sector counts, which we copy to the new key in
ec_stripe_key_update.
But the device removal path can now invalidate stripe pointers to a
device, and that can race with stripe reuse.
Change ec_stripe_key_update() to check for and resolve this
inconsistency.

Check if we have snapshot_trees or subvolumes that refer to the snapshot
node being reconstructed, and use them.
With this, the kill_btree_root test that blows away the snapshots btree
now passes, and we're able to successfully reconstruct.

This kselftest update for Linux 6.12-rc3 consists of several fixes
for build, run-time errors, and reporting errors:
-- ftrace: regression test for a kernel crash when running function graph
tracing and then enabling function profiler.
-- rseq: fix for mm_cid test failure.
-- vDSO:
- fixes to reporting skip and other error conditions.
- changes unconditionally build chacha and getrandom tests on
all architectures to make it easier for them to run in CIs.
- build error when sched.h to bring in CLONE_NEWTIME define.

Fix rcuog kthread wakeup invocation from softirq context on a CPU
which has been marked offline. This can happen when new callbacks
are enqueued from a softirq on an offline CPU before it calls
rcutree_report_cpu_dead(). When this happens on NOCB configuration,
the rcuog wake-up is deferred through an IPI to an online CPU.
This is done to avoid call into the scheduler which can risk
arming the RT-bandwidth after hrtimers have been migrated out
and disabled. However, doing IPI call from softirq is not allowed
Fix this by forcing deferred rcuog wakeup through the NOCB timer
when the CPU is offline.

come back as a regression.

Unlike EMR tools which encode type information in their tool ID, tools
for AES sensors are all "generic pens". It is inappropriate to make use
of the wacom_intuos_get_tool_type function when dealing with these kinds
of devices. Instead, we should only ever report BTN_TOOL_PEN or
BTN_TOOL_RUBBER, as depending on the state of the Eraser and Invert
bits.
