btrfs: do not strictly require dirty metadata threshold for metadata writepages
[BUG]
There is an internal report that over 1000 processes are
waiting at the io_schedule_timeout() of balance_dirty_pages(), causing
a system hang and trigger a kernel coredump.
The kernel is v6.4 kernel based, but the root problem still applies to
any upstream kernel before v6.18.
[CAUSE]
From Jan Kara for his wisdom on the dirty page balance behavior first.
This cgroup dirty limit was what was actually playing the role here
because the cgroup had only a small amount of memory and so the dirty
limit for it was something like 16MB.
Dirty throttling is responsible for enforcing that nobody can dirty
(significantly) more dirty memory than there's dirty limit. Thus when
a task is dirtying pages it periodically enters into balance_dirty_pages()
and we let it sleep there to slow down the dirtying.
When the system is over dirty limit already (either globally or within
a cgroup of the running task), we will not let the task exit from
balance_dirty_pages() until the number of dirty pages drops below the
limit.
So in this particular case, as I already mentioned, there was a cgroup
with relatively small amount of memory and as a result with dirty limit
set at 16MB. A task from that cgroup has dirtied about 28MB worth of
pages in btrfs btree inode and these were practically the only dirty
pages in that cgroup.
So that means the only way to reduce the dirty pages of that cgroup is
to writeback the dirty pages of btrfs btree inode, and only after that
those processes can exit balance_dirty_pages().
Now back to the btrfs part, btree_writepages() is responsible for
writing back dirty btree inode pages.
The problem here is, there is a btrfs internal threshold that if the
btree inode's dirty bytes are below the 32M threshold, it will not
do any writeback.
This behavior is to batch as much metadata as possible so we won't write
back those tree blocks and then later re-COW them again for another
modification.
This internal 32MiB is higher than the existing dirty page size (28MiB),
meaning no writeback will happen, causing a deadlock between btrfs and
cgroup:
- Btrfs doesn't want to write back btree inode until more dirty pages
- Cgroup/MM doesn't want more dirty pages for btrfs btree inode
Thus any process touching that btree inode is put into sleep until
the number of dirty pages is reduced.
Thanks Jan Kara a lot for the analysis of the root cause.

thermal: renesas: rzg3e: add support for RZ/T2H and RZ/N2H
The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs expose the temperature calibration via SMC SIP and do not have a reset for the TSU peripheral, and use different minimum and maximum temperature values compared to the already supported RZ/G3E. Although the calibration data is stored in an OTP memory, the OTP itself is not memory-mapped, access to it is done through an OTP controller. The OTP controller is only accessible from the secure world, but the temperature calibration data stored in the OTP is exposed via SMC. Add support for retrieving the calibration data using arm_smcc_smc(). Add a compatible for RZ/T2H, RZ/N2H can use it as a fallback.

The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs include a Temperature Sensor Unit (TSU). The device provides real-time temperature measurements for thermal management, utilizing a single dedicated channel for temperature sensing. Compared to the previously supported RZ/G3E, the RZ/T2H and RZ/N2H SoCs do not have a reset for the TSU peripheral, and the OTP data is exposed via ARM SMC, as opposed to a system register.

drm/i915/display: Prevent u64 underflow in intel_fbc_stolen_end
Static analysis reveals a potential integer underflow in
intel_fbc_stolen_end. This can apparently occur if
intel_parent_stolen_area_size returns zero (or, theoretically, any value
less than 2^23), as 2^23 is subtracted from the return value and stored
in a u64. While this doesn't appear to cause any issues due to the use
of the min() function to clamp the return values from the
intel_fbc_stolen_end function, it would be best practice to avoid
undeflowing values like this on principle. So, rework the function to
prevent the underflow from occurring. Note that the underflow at
present would result in the value of intel_fbc_cfb_base_max being
returned at the end of intel_fbc_stolen_end, so just return that if the
value of intel_parent_stolen_area_size is too small.
While we're here, fix the other comments here and modify the execution
path for readability.
v2: (Jani)
- Fix the comments in intel_fbc_stolen_end
- Use check_sub_overflow
- Remove macro that mirrors SZ_8M, as it is now only referenced once
- Misc. formatting fixes

thermal: renesas: rzg3e: make calibration value retrieval per-chip
The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs expose the temperature calibration data via SMC SIP calls. To prepare for supporting these SoCs, do the following changes. Rename rzg3e_thermal_parse_dt() to rzg3e_thermal_get_syscon_trim(). Move the syscon usage out of rzg3e_thermal_get_calibration() and into rzg3e_thermal_get_syscon_trim() and remove single-use variables from the private state. Place a pointer to rzg3e_thermal_get_syscon_trim() into the chip-specific struct, and use it in the probe function to retrieve the calibration values. Now that syscon usage has been moved out of rzg3e_thermal_get_calibration(), remove it and inline the calibration validation into the probe function. Also, reuse the TSU_CODE_MAX macro to mask the calibration values, as GEMASK(11, 0) and 0xFFF are equivalent, and replace the hardcoded 0xFFF with TSU_CODE_MAX in the calibration validation.

pwm: tiehrpwm: Enable pwmchip's parent device before setting configuration
The period and duty cycle configurations on J7200 and J784S4 SoCs
does not get reflected after setting them using sysfs nodes.
This is because at the end of ehrpwm_pwm_config function,
the put_sync function is called which resets the hardware.
Hold the PWM controller out of low-power mode during .apply() to
make sure it accepts the writes to its registers.
This renders the calls to pm_runtime_get_sync() and
pm_runtime_put_sync() in ehrpwm_pwm_config() into no-ops, so
these can be dropped.

bpf: support bpf_get_func_arg() for BPF_TRACE_RAW_TP
For now, bpf_get_func_arg() and bpf_get_func_arg_cnt() is not supported by the BPF_TRACE_RAW_TP, which is not convenient to get the argument of the tracepoint, especially for the case that the position of the arguments in a tracepoint can change. The target tracepoint BTF type id is specified during loading time, therefore we can get the function argument count from the function prototype instead of the stack.

ASoC: SDCA: Add NO_DIRECT_COMPLETE flag to class driver
The SDCA class driver currently expects the device will be fully powered
down on system suspend but not on runtime suspend. This is typically
required as when audio is not active (ie. runtime suspend) jack detect
is expected to still function, but when the whole system is hibernated
there is no need to recognise audio jack events. This means the class
driver needs to always be informed of a system suspend, so the direct
complete optimisation (where PM will skip calling system suspend if the
device is runtime suspended) is not appropriate for the SDCA class
driver.
Add the NO_DIRECT_COMPLETE flag to prevent this optimisation from
running against this driver.

dt-bindings: thermal: r9a09g047-tsu: Document RZ/V2N TSU
The Renesas RZ/V2N SoC includes a Thermal Sensor Unit (TSU) block designed to measure the junction temperature. The device provides real-time temperature measurements for thermal management, utilizing two dedicated channels for temperature sensing. The Renesas RZ/V2N SoC is using the same TSU IP found on the RZ/G3E SoC, the only difference being that it has two channels instead of one. Add new compatible string "renesas,r9a09g056-tsu" for RZ/V2N and use "renesas,r9a09g047-tsu" as a fallback compatible to indicate hardware compatibility with the RZ/G3E implementation.

dm: fix excessive blk-crypto operations for invalid keys
dm_exec_wrappedkey_op() passes through the derive_sw_secret, import_key,
generate_key, and prepare_key blk-crypto operations to an underlying
device.
Currently, it calls the operation on every underlying device until one
returns success.
This logic is flawed when the operation is expected to fail, such as an
invalid key being passed to derive_sw_secret. That can happen if
userspace passes an invalid key to the FS_IOC_ADD_ENCRYPTION_KEY ioctl.
When that happens on a device-mapper device that consists of many
dm-linear targets, a lot of unnecessary key unwrapping requests get sent
to the underlying key wrapping hardware.
Fix this by considering the first device only. As already documented in
the comment, it was already checked that all underlying devices support
wrapped keys, so this should be fine.

soc/tegra: Changes for v6.20-rc1
This series primarily refactors the Tegra PMC driver to eliminate reliance on a global variable, transitioning to passing the tegra_pmc context explicitly across clocks, powergates, sysfs/debugfs interfaces, and power management callbacks. Additionally, it resolves a warning during system resume by deferring an unsafe generic_handle_irq() call to a hard IRQ context using irq_work. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiOrDCAFJzPfAjcif3SOs138+s6EFAmlskJUACgkQ3SOs138+ s6EIaQ//WtuuMjXFkxbNPgO3IuRsYuQIswHZouMkRSQJWeWAddRYpO5mE4QIaGYc h0pdJp0tnvwO8rMQT06ipCn2UG25WnkqNeRFv1BUKDcrMV19wi4qqONGZXOaeQAW EDnGq2ya3laZKstgJbMlpnbD0sAVt1TggH8Dm8ayTvxb5A9kCFnjTsHIGot53i+q Nmm46XHKX6noN6Xw3RCUch/CgmfDdga/nSDtrlxV0GNUFphONxA9N9dRQLSBOEt1 IDOyojJhCMQ9FKMSEJa4q0llkGZBO2U7zMnl7COeMYQIG8riITu5y9OqWZorqpEL cpvUZqu8hya3FhJyBkQhbJ/LBniSX6PNMoLdataOXWhW59IBBKr13W5IMKZN0sK2 82eSSyI7FOF7WwyQ6JxVN31PxCT8/+2qIzv8xblmuGJ3fnkUu5I0R0dH89ukVFCp aiDp28bVrGCmEsoUE7Ld7p+CIpnflpm4/oshX6bPkW3EGEQBa+ljU8UrKchNkZaz Vb0NM8qORQiR09WuIzWzVcG1J39hAf+8w6QxSXaz92GOclf827XyqQ/ICt222jaN XMDUCuw2pBopoIwIzMaH7nFeXY6WHTUWwwOapBfX05diJZUEJ0+RPc+KIOqoQjFG i6fyOJfHgAbJV/d/C0ob+xS6/bn1IFFt+WJ4JwPVTM/pYUpFt+k= =OVOm -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmlw8eoACgkQmmx57+YA GNkc4g//Uf/rXcaunqiTEhP6NgQ2WFGTpmEo0RVqS70sEWno0koOU1JOUmCohuem IKkF2MmO7Dr3l6wqpgYYY+VUgtQQG6gWIEODby4XTS1FM1yK4y+49vafudeQFcA9 oA0QmneMlsyfXEqVQZv0Xo3nN+Us3xfRT8AXsSh8pIFlugJ2WNeF+lpX2y/0gERm RaY/vwSM2w664++ykG1dS+t6gP8+AUumO1wMJJhK7annNDPZKybS6xGdme1Lx5iK Y+N3naYRCwXKCb4oXC2eJ8N5QQBAxIgEh6PLKdsODCHjiMpQCvOPZE0LUN66mwaV QUbXIs786KKEVt0QW8YGyZ6YptZ/Xeph6jIGBAfM9+69qPFCjQLQTxi/HBwIo4R0 NL7rhltkUTt3WjqzVuuPQlOyYLB6wn2UHA2EyVT2y1z93gEWSIP5N4MBPHrJ0Not hS/625emNDbFMxU3MOx3fsQ6r9hS5mMvDQhbhgRNo+5cLnivtuTNj8CKCcbpYDRS 2e+DHvEJsq0zcKm+I+Nap7BTNoiJ5mYMXyqiz8KNWmfD+bm7BmiWm7QPsXsDF1h9 fzzZ1RYDI5bDutC1YdKP64NkSs5iev6IaDS0YTrisajPV5KshLt0vzeX9wUnt+pX aoTZK2zTDyc0LiD2KSEk0Srvh6SkApc/zk6nU+jsJVBlEGys7Do= =ii5w -----END PGP SIGNATURE----- Merge tag 'tegra-for-6.20-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into soc/drivers soc/tegra: Changes for v6.20-rc1 This series primarily refactors the Tegra PMC driver to eliminate reliance on a global variable, transitioning to passing the tegra_pmc context explicitly across clocks, powergates, sysfs/debugfs interfaces, and power management callbacks.

perf/x86/intel: Do not enable BTS for guests
By default when users program perf to sample branch instructions (PERF_COUNT_HW_BRANCH_INSTRUCTIONS) with a sample period of 1, perf interprets this as a special case and enables BTS (Branch Trace Store) as an optimization to avoid taking an interrupt on every branch. Since BTS doesn't virtualize, this optimization doesn't make sense when the request originates from a guest. Add an additional check that prevents this optimization for virtualized events (exclude_host). Reported-by: Jan H.

perf: Fix refcount warning on event->mmap_count increment
When calling refcount_inc(&event->mmap_count) inside perf_mmap_rb(), the
following warning is triggered:
refcount_t: addition on 0; use-after-free.
WARNING: lib/refcount.c:25
PoC:
struct perf_event_attr attr = {0};
int fd = syscall(__NR_perf_event_open, &attr, 0, -1, -1, 0);
mmap(NULL, 0x3000, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);
int victim = syscall(__NR_perf_event_open, &attr, 0, -1, fd,
PERF_FLAG_FD_OUTPUT);
mmap(NULL, 0x3000, PROT_READ | PROT_WRITE, MAP_SHARED, victim, 0);
This occurs when creating a group member event with the flag
PERF_FLAG_FD_OUTPUT. The group leader should be mmap-ed and then mmap-ing
the event triggers the warning.
Since the event has copied the output_event in perf_event_set_output(),
event->rb is set. As a result, perf_mmap_rb() calls
refcount_inc(&event->mmap_count) when event->mmap_count = 0.
Disallow the case when event->mmap_count = 0. This also prevents two
events from updating the same user_page.

Arm SCMI updates for v7.0
A set of cleanups, refactoring, and fixes to the Arm SCMI stack:
1. Rework protocol version negotiation by moving version discovery and
downgrade handling into the SCMI core and performing negotiation early,
before protocol initialization. Remove legacy per-protocol versioning
logic now made redundant by centralized SCMI handling.
2. Increase the internal MAX_OPPS limit in the SCMI performance protocol
to 64, allowing platforms with larger OPP tables to be fully supported.
3. Reduce duplicated boilerplate in pinctrl and related protocols by
consolidating validation and lookup logic in protocol get info helpers.
4. Refactor reset protocol domain handling by introducing a shared lookup
helper, ensuring consistent validation and error reporting.
5. Fix potential undefined behaviour by properly initializing pointers
annotated with the __free attribute.

nvmet: fix race in nvmet_bio_done() leading to NULL pointer dereference
There is a race condition in nvmet_bio_done() that can cause a NULL
pointer dereference in blk_cgroup_bio_start():
1. nvmet_bio_done() is called when a bio completes
2. nvmet_req_complete() is called, which invokes req->ops->queue_response(req)
3. The queue_response callback can re-queue and re-submit the same request
4. The re-submission reuses the same inline_bio from nvmet_req
5. Meanwhile, nvmet_req_bio_put() (called after nvmet_req_complete)
invokes bio_uninit() for inline_bio, which sets bio->bi_blkg to NULL
6. The re-submitted bio enters submit_bio_noacct_nocheck()
7. blk_cgroup_bio_start() dereferences bio->bi_blkg, causing a crash:
BUG: kernel NULL pointer dereference, address: 0000000000000028
#PF: supervisor read access in kernel mode
RIP: 0010:blk_cgroup_bio_start+0x10/0xd0
Call Trace:
submit_bio_noacct_nocheck+0x44/0x250
nvmet_bdev_execute_rw+0x254/0x370 [nvmet]
process_one_work+0x193/0x3c0
worker_thread+0x281/0x3a0
Fix this by reordering nvmet_bio_done() to call nvmet_req_bio_put()
BEFORE nvmet_req_complete(). This ensures the bio is cleaned up before
the request can be re-submitted, preventing the race condition.
