This turned out to have several bugs, which were missed because the fsck

Kicking it out for now, hopefully it can make 6.15.

a6250aa251 ("sched_ext: Handle cases where pick_task_scx() is called
without preceding balance_scx()") added a workaround to handle the cases
where pick_task_scx() is called without prececing balance_scx() which is due
to a fair class bug where pick_taks_fair() may return NULL after a true
return from balance_fair().
The workaround detects when pick_task_scx() is called without preceding
balance_scx() and emulates SCX_RQ_BAL_KEEP and triggers kicking to avoid
stalling. Unfortunately, the workaround code was testing whether @prev was
on SCX to decide whether to keep the task running. This is incorrect as the
task may be on SCX but no longer runnable.
This could lead to a non-runnable task to be returned from pick_task_scx()
which cause interesting confusions and failures. e.g. A common failure mode
is the task ending up with (!on_rq && on_cpu) state which can cause
potential wakers to busy loop, which can easily lead to deadlocks.
Fix it by testing whether @prev has SCX_TASK_QUEUED set. This makes
@prev_on_scx only used in one place. Open code the usage and improve the
comment while at it.

- A fix for the rseq selftests, which was using an invalid constraint.
- A pair of fixes for signal frame size handling:
- We were reserving space for an extra empty extension context
header on systems with extended signal context, thus resulting in
unnecessarily large allocations.
- We weren't properly checking for available extensions before
calculating the signal stack size, which resulted in undersized
stack allocations on some systems (at least those with T-Head
custom vectors).

Pull tracing fixes from Steven Rostedt:
"Function graph accounting fixes:
- Fix the manage ops hashes
The function graph registers a "manager ops" and "sub-ops" to
ftrace. The manager ops does not have any callback but calls the
sub-ops callbacks. The manage ops hashes (what is used to tell
ftrace what functions to attach to) is built on the sub-ops it
manages.
There was an error in the way it built the hash. An empty hash
means to attach to all functions. When the manager ops had one
sub-ops it properly copied its hash. But when the manager ops had
more than one sub-ops, it went into a loop to make a set of all
functions it needed to add to the hash. If any of the subops hashes
was empty, that would mean to attach to all functions. The error
was that the first iteration of the loop passed in an empty hash to
start with in order to add the other hashes. That starting hash was
mistaken as to attach to all functions. This made the manage ops
attach to all functions whenever it had two or more sub-ops, even
if each sub-op was attached to only a single function.
- Do not add duplicate entries to the manager ops hash
If two or more subops hashes trace the same function, an entry for
that function will be added to the manager ops for each subops.
This causes waste and extra overhead.
Fprobe accounting fixes:
- Remove last function from fprobe hash
Fprobes has a ftrace hash to manage which functions an fprobe is
attached to. It also has a counter of how many fprobes are
attached. When the last fprobe is removed, it unregisters the
fprobe from ftrace but does not remove the functions the last
fprobe was attached to from the hash. This leaves the old functions
attached. When a new fprobe is added, the fprobe infrastructure
attaches to not only the functions of the new fprobe, but also to
the functions of the last fprobe.
- Fix accounting of the fprobe counter
When a fprobe is added, it updates a counter. If the counter goes
from zero to one, it attaches its ops to ftrace. When an fprobe is
removed, the counter is decremented. If the counter goes from 1 to
zero, it removes the fprobes ops from ftrace.
There was an issue where if two fprobes trace the same function,
the addition of each fprobe would increment the counter. But when
removing the first of the fprobes, it would notice that another
fprobe is still attached to one of its functions no it does not
remove the functions from the ftrace ops.
But it also did not decrement the counter, so when the last fprobe
is removed, the counter is still one. This leaves the fprobes
callback still registered with ftrace and it being called by the
functions defined by the fprobes ops hash. Worse yet, because all
the functions from the fprobe ops hash have been removed, that
tells ftrace that it wants to trace all functions.
Thus, this puts the state of the system where every function is
calling the fprobe callback handler (which does nothing as there
are no registered fprobes), but this causes a good 13% slow down of
the entire system.
Other updates:
- Add a selftest to test the above issues to prevent regressions.
- Fix preempt count accounting in function tracing
Better recursion protection was added to function tracing which
added another layer of preempt disable. As the preempt_count gets
traced in the event, it needs to subtract the amount of preempt
disabling the tracer does to record what the preempt_count was when
the trace was triggered.
- Fix memory leak in output of set_event
A variable is passed by the seq_file functions in the location that
is set by the return of the next() function. The start() function
allocates it and the stop() function frees it. But when the last
item is found, the next() returns NULL which leaks the data that
was allocated in start(). The m->private is used for something
else, so have next() free the data when it returns NULL, as stop()
will then just receive NULL in that case"

Pull io_uring fixes from Jens Axboe:
- Series fixing an issue with multishot read on pollable files that may
return -EIOCBQUEUED from ->read_iter(). Four small patches for that,
the first one deliberately done in such a way that it'd be easy to
backport
- Remove some dead constant definitions

Pull gpio fixes from Bartosz Golaszewski:
"There are two fixes for GPIO core: one adds missing retval checks to
older code, while the second adds SRCU synchronization to legs in code

- check the return value of the get_direction() callback in struct
gpio_chip
- protect the multi-line get/set legs in GPIO core with SRCU
- fix a race condition in gpio-vf610"

The root cause is that s_next() returns NULL when nothing is found.
This results in s_stop() attempting to free a NULL pointer because its
parameter is NULL.
Fix the issue by freeing the memory appropriately when s_next() fails
to find anything.

The function tracer should record the preemption level at the point when
the function is invoked. If the tracing subsystem decrement the
preemption counter it needs to correct this before feeding the data into
the trace buffer. This was broken in the commit cited below while
shifting the preempt-disabled section.
Use tracing_gen_ctx_dec() which properly subtracts one from the
preemption counter on a preemptible kernel.
