Pull tracing updates from Steven Rostedt:
- Add option traceoff_after_boot
In order to debug kernel boot, it sometimes is helpful to enable
tracing via the kernel command line. Unfortunately, by the time the
login prompt appears, the trace is overwritten by the init process
and other user space start up applications.
Adding a "traceoff_after_boot" will disable tracing when the kernel
passes control to init which will allow developers to be able to see
the traces that occurred during boot.
- Clean up the mmflags macros that display the GFP flags in trace
events
The macros to print the GFP flags for trace events had a bit of
duplication. The code was restructured to remove duplication and in
the process it also adds some flags that were missed before.
- Removed some dead code and scripts/draw_functrace.py
draw_functrace.py hasn't worked in years and as nobody complained
about it, remove it.
- Constify struct event_trigger_ops
The event_trigger_ops is just a structure that has function pointers
that are assigned when the variables are created. These variables
should all be constants.
- Other minor clean ups and fixes

Pull latency tracing updates from Steven Rostedt:
- Add some trace events to osnoise and timerlat sample generation
This adds more information to the osnoise and timerlat tracers as
well as allows BPF programs to be attached to these locations to
extract even more data.
- Fix to DECLARE_TRACE_CONDITION() macro
It wasn't used but now will be and it happened to be broken causing
the build to fail.
- Add scheduler specification monitors to runtime verifier (RV)
This is a continuation of Daniel Bristot's work.
RV allows monitors to run and react concurrently. Running the
cumulative model is equivalent to running single components using the
same reactors, with the advantage that it's easier to point out which
specification failed in case of error.
This update introduces nested monitors to RV, in short, the sysfs
monitor folder will contain a monitor named sched, which is nothing
but an empty container for other monitors. Controlling the sched
monitor (enable, disable, set reactors) controls all nested monitors.
The following scheduling monitors are added:
- sco: scheduling context operations
Monitor to ensure sched_set_state happens only in thread context
- tss: task switch while scheduling
Monitor to ensure sched_switch happens only in scheduling context
- snroc: set non runnable on its own context
Monitor to ensure set_state happens only in the respective task's context
- scpd: schedule called with preemption disabled
Monitor to ensure schedule is called with preemption disabled
- snep: schedule does not enable preempt
Monitor to ensure schedule does not enable preempt
- sncid: schedule not called with interrupt disabled
Monitor to ensure schedule is not called with interrupt disabled

Pull ftrace updates from Steven Rostedt:
- Record function parameters for function and function graph tracers
An option has been added to function tracer (func-args) and the
function graph tracer (funcgraph-args) that when set, the tracers
will record the registers that hold the arguments into each function
event. On reading of the trace, it will use BTF to print those
arguments. Most archs support up to 6 arguments (depending on the
complexity of the arguments) and those are printed.
If a function has more arguments then what was recorded, the output
will end with " ... )".
Example of function graph tracer:
6) | dummy_xmit [dummy](skb = 0x8887c100, dev = 0x872ca000) {
6) | consume_skb(skb = 0x8887c100) {
6) | skb_release_head_state(skb = 0x8887c100) {
6) 0.178 us | sock_wfree(skb = 0x8887c100)
6) 0.627 us | }
- The rest of the changes are minor clean ups and fixes

Pull tracing / sorttable updates from Steven Rostedt:
- Implement arm64 build time sorting of the mcount location table
When gcc is used to build arm64, the mcount_loc section is all zeros
in the vmlinux elf file. The addresses are stored in the Elf_Rela
location.
To sort at build time, an array is allocated and the addresses are
added to it via the content of the mcount_loc section as well as he
Elf_Rela data. After sorting, the information is put back into the
Elf_Rela which now has the section sorted.
- Make sorting of mcount location table for arm64 work with clang as
well
When clang is used, the mcount_loc section contains the addresses,
unlike the gcc build. An array is still created and the sorting works
for both methods.
- Remove weak functions from the mcount_loc section
Have the sorttable code pass in the data of functions defined via
'nm -S' which shows the functions as well as their sizes. Using this
information the sorttable code can determine if a function in the
mcount_loc section was weak and overridden. If the function is not
found, it is set to be zero. On boot, when the mcount_loc section is
read and the ftrace table is created, if the address in the
mcount_loc is not in the kernel core text then it is removed and not
added to the ftrace_filter_functions (the functions that can be
attached by ftrace callbacks).
- Update and fix the reporting of how much data is used for ftrace
functions
On boot, a report of how many pages were used by the ftrace table as
well as how they were grouped (the table holds a list of sections
that are groups of pages that were able to be allocated). The
removing of the weak functions required the accounting to be updated.

Pull bcachefs updates from Kent Overstreet:
"On disk format is now soft frozen: no more required/automatic are
anticipated before taking off the experimental label.
Major changes/features since 6.14:
- Scrub
- Blocksize greater than page size support
- A number of "rebalance spinning and doing no work" issues have been
fixed; we now check if the write allocation will succeed in
bch2_data_update_init(), before kicking off the read.
There's still more work to do in this area. Later we may want to
add another bitset btree, like rebalance_work, to track "extents
that rebalance was requested to move but couldn't", e.g. due to
destination target having insufficient online devices.
- We can now support scaling well into the petabyte range: latest
bcachefs-tools will pick an appropriate bucket size at format time
to ensure fsck can run in available memory (e.g. a server with
256GB of ram and 100PB of storage would want 16MB buckets).
On disk format changes:
- 1.21: cached backpointers (scalability improvement)
Cached replicas now get backpointers, which means we no longer rely
on incrementing bucket generation numbers to invalidate cached
data: this lets us get rid of the bucket generation number garbage
collection, which had to periodically rescan all extents to
recompute bucket oldest_gen.
Bucket generation numbers are now only used as a consistency check,
but they're quite useful for that.
- 1.22: stripe backpointers
Stripes now have backpointers: erasure coded stripes have their own
checksums, separate from the checksums for the extents they contain
(and stripe checksums also cover the parity blocks). This is
required for implementing scrub for stripes.
- 1.23: stripe lru (scalability improvement)
Persistent lru for stripes, ordered by "number of empty blocks".
This is used by the stripe creation path, which depending on free
space may create a new stripe out of a partially empty existing
stripe instead of starting a brand new stripe.
This replaces an in-memory heap, and means we no longer have to
read in the stripes btree at startup.
- 1.24: casefolding
Case insensitive directory support, courtesy of Valve.
This is an incompatible feature, to enable mount with
-o version_upgrade=incompatible
- 1.25: extent_flags
Another incompatible feature requiring explicit opt-in to enable.
This adds a flags entry to extents, and a flag bit that marks
extents as poisoned.
A poisoned extent is an extent that was unreadable due to checksum
errors. We can't move such extents without giving them a new
checksum, and we may have to move them (for e.g. copygc or device
evacuate). We also don't want to delete them: in the future we'll
have an API that lets userspace ignore checksum errors and attempt
to deal with simple bitrot itself. Marking them as poisoned lets us
continue to return the correct error to userspace on normal read
calls.
Other changes/features:
- BCH_IOCTL_QUERY_COUNTERS: this is used by the new 'bcachefs fs top'
command, which shows a live view of all internal filesystem
counters.
- Improved journal pipelining: we can now have 16 journal writes in
flight concurrently, up from 4. We're logging significantly more to
the journal than we used to with all the recent disk accounting
changes and additions, so some users should see a performance
increase on some workloads.
- BCH_MEMBER_STATE_failed: previously, we would do no IO at all to
devices marked as failed. Now we will attempt to read from them,
but only if we have no better options.
- New option, write_error_timeout: devices will be kicked out of the
filesystem if all writes have been failing for x number of seconds.
We now also kick devices out when notified by blk_holder_ops that
they've gone offline.
- Device option handling improvements: the discard option should now
be working as expected (additionally, in -tools, all device options
that can be set at format time can now be set at device add time,
i.e. data_allowed, state).
- We now try harder to read data after a checksum error: we'll do
additional retries if necessary to a device after after it gave us
data with a checksum error.
- More self healing work: the full inode <-> dirent consistency
checks that are currently run by fsck are now also run every time
we do a lookup, meaning we'll be able to correct errors at runtime.
Runtime self healing will be flipped on after the new changes have
seen more testing, currently they're just checking for consistency.
- KMSAN fixes: our KMSAN builds should be nearly clean now, which
will put a massive dent in the syzbot dashboard"

Pull btrfs updates from David Sterba:
"User visible changes:
- fall back to buffered write if direct io is done on a file that
requires checksums
- this avoids a problem with checksum mismatch errors, observed
e.g. on virtual images when writes to pages under writeback
cause the checksum mismatch reports
- this may lead to some performance degradation but currently the
recommended setup for VM images is to use the NOCOW file
attribute that also disables checksums
- fast/realtime zstd levels -15 to -1
- supported by mount options (compress=zstd:-5) and defrag ioctl
- improved speed, reduced compression ratio, check the commit for
sample measurements
- defrag ioctl extended to accept negative compression levels
- subpage mode
- remove warning when subpage mode is used, the feature is now
reasonably complete and tested
- in debug mode allow to create 2K b-tree nodes to allow testing
subpage on x86_64 with 4K pages too
Performance improvements:
- in send, better file path caching improves runtime (on sample load
by -30%)
- on s390x with hardware zlib support prepare the input buffer in a
better way to get the best results from the acceleration
- minor speed improvement in encoded read, avoid memory allocation in
synchronous mode
Core:
- enable stable writes on inodes, replacing manually waiting for
writeback and allowing to skip that on inodes without checksums
- add last checks and warnings for out-of-band dirty writes to pages,
requiring a fixup ("fixup worker"), this should not be necessary
since 5.8 where get_user_page() and pin_user_pages*() prevent this
- long history behind that, we'll be happy to remove the whole
infrastructure in the near future
- more folio API conversions and preparations for large folio support
- subpage cleanups and refactoring, split handling of data and
metadata to allow future support for large folios
- readpage works as block-by-block, no change for normal mode, this
is preparation for future subpage updates
- block group refcount fixes and hardening
- delayed iput fixes
- in zoned mode, fix zone activation on filesystem with missing
devices

DTS example in the bindings should be indented with 2- or 4-spaces and
aligned with opening '- |', so correct any differences like 3-spaces or
mixtures 2- and 4-spaces in one binding.
No functional changes here, but saves some comments during reviews of
new patches built on existing code.

- Create pwrctrl devices in pci_scan_device() to make it more symmetric
with pci_pwrctrl_unregister() and make pwrctrl devices for PCI bridges
possible (Manivannan Sadhasivam)
- Unregister pwrctrl devices in pci_destroy_dev() so DOE, ASPM, etc. can
still access devices after pci_stop_dev() (Manivannan Sadhasivam)
- If there's a pwrctrl device for a PCI device, skip scanning it because
the pwrctrl core will rescan the bus after the device is powered on
(Manivannan Sadhasivam)
- Add a pwrctrl driver for PCI slots based on voltage regulators described
via devicetree (Manivannan Sadhasivam)
* pci/pwrctrl:
