git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this round, we've made more work into per-file compression support.
For example, F2FS_IOC_GET | SET_COMPRESS_OPTION provides a way to
change the algorithm or cluster size per file. F2FS_IOC_COMPRESS |
DECOMPRESS_FILE provides a way to compress and decompress the existing
normal files manually.
There is also a new mount option, compress_mode=fs|user, which can
control who compresses the data.
Chao also added a checksum feature with a mount option so that
we are able to detect any corrupted cluster.
In addition, Daniel contributed casefolding with encryption patch,
which will be used for Android devices.
Summary:
Enhancements:
- add ioctls and mount option to manage per-file compression feature
- support casefolding with encryption
- support checksum for compressed cluster
- avoid IO starvation by replacing mutex with rwsem
- add sysfs, max_io_bytes, to control max bio size
Bug fixes:
- fix use-after-free issue when compression and fsverity are enabled
- fix consistency corruption during fault injection test
- fix data offset for lseek
- get rid of buffer_head which has 32bits limit in fiemap
- fix some bugs in multi-partitions support
- fix nat entry count calculation in shrinker
- fix some stat information
And, we've refactored some logics and fix minor bugs as well"

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull IOMMU updates from Will Deacon:
"There's a good mixture of improvements to the core code and driver
changes across the board.
One thing worth pointing out is that this includes a quirk to work
around behaviour in the i915 driver (see 65f746e8285f ("iommu: Add
quirk for Intel graphic devices in map_sg")), which otherwise
interacts badly with the conversion of the intel IOMMU driver over to
the DMA-IOMMU APU but has being fixed properly in the DRM tree.
We'll revert the quirk later this cycle once we've confirmed that
things don't fall apart without it.
Summary:
- IOVA allocation optimisations and removal of unused code
- Introduction of DOMAIN_ATTR_IO_PGTABLE_CFG for parameterising the
page-table of an IOMMU domain
- Support for changing the default domain type in sysfs
- Optimisation to the way in which identity-mapped regions are
created
- Driver updates:
* Arm SMMU updates, including continued work on Shared Virtual
Memory
* Tegra SMMU updates, including support for PCI devices
* Intel VT-D updates, including conversion to the IOMMU-DMA API
- Cleanup, kerneldoc and minor refactoring"

The kernel cmdline reboot= option offers some sort of control on how the
reboot is issued.
We don't always know in advance what type of reboot to perform.
Sometimes a warm reboot is preferred to persist certain memory regions
across the reboot. Others a cold one is needed to apply a future system
update that makes a memory memory model change, like changing the base
page size or resizing a persistent memory region.
Or simply we want to enable reboot_force because we noticed that
something bad happened.
Add handles in sysfs to allow setting these reboot options, so they can
be changed when the system is booted, other than at boot time.
The handlers are under <sysfs>/kernel/reboot, can be read to get the
current configuration and written to alter it.
# cd /sys/kernel/reboot/
# grep . *
cpu:0
force:0
mode:cold
type:acpi
# echo 2 >cpu
# echo yes >force
# echo soft >mode
# echo bios >type
# grep . *
cpu:2
force:1
mode:soft
type:bios
Before setting anything, check for CAP_SYS_BOOT capability, so it's
possible to allow an unpriviledged process to change these settings simply
by relaxing the handles permissions, without opening them to the world.

Pull devfreq updates for 5.11 from Chanwoo Choi:
1. Update devfreq core
- Add new devfreq_frequency tracepoint to show the frequency change
information.
- Add governor feature flag. The devfreq governor is able to set the
specific flag in order to support a non-common feature. For
example, if the governor supports the 'immutable' feature, don't
allow user space to change the governor via sysfs.
- Add governor sysfs attribute flag for each sysfs file. Prior to that
the devfreq subsystem allowed all of the sysfs files to be accessed
regardless of the governor type. But some sysfs fils are not
supported by specific devfreq governors. In order to only allow the
sysfs files supported by the governor to be accessed, clarify the
access permissions of sysfs attributes according to the governor.
When adding the devfreq governor, specify the available attribute
information by using DEVFREQ_GOV_ATTR_* symbols. The user can read
or write the sysfs attributes in accordance to the specified
access permissions.
- Clean-up the code to reduce duplication for the devfreq tracepoint
and to remove redundant governor_name field from struct devfreq.
2. Update exynos-bus.c devfreq driver
- Add interconnect API support to the Samsung Exynos Bus Frequency
driver, exynos-bus.c. Complementing the devfreq driver with
interconnect functionality allows to ensure that the QoS
requirements regarding devices accessing the system memory (e.g.
video processing devices) will be met and allows to avoid issues
like DMA underrun.
3. Update tegra devfreq driver
- Add interconnect support and OPP interface to tegra30-devfreq.c.
Also, it is to guarantee the QoS requirement of some devices like
the display controller.
- Move tegra20-devfreq.c from drivers/devfreq/ into drivers/memory/tegra/
in order to use the more proper monitoring feature such as EMC_STAT
which is located in drivers/memory/tegra/.
- Separate the configuration information for different SoCs in
tegra30-devfrqe.c. The tegra30-devfreq.c had been supporting both
tegra30-actmon and tegra124-actmon devices. In order to use the
more correct configuration data, separate them.
- Use dev_err_probe() to handle the deferred probe error in
tegra30-devfreq.c.
4. Pull the request of 'Tegra SoC and clock controller changes for
v5.11' sent by Krzysztof Kozlowski <krzk@kernel.org> in order to
avoid a build error."

This patch adds max_io_bytes to limit bio size when f2fs tries to merge
consecutive IOs. This can give a testing point to split out bios and check
end_io handles those bios correctly. This is used to capture a recent bug

While PCI power states D0-D3hot can be queried from user-space via lspci,
D3cold cannot. lspci cannot provide an accurate value when the device is
in D3cold as it has to restore the device to D0 before it can access its
power state via the configuration space, leading to it reporting D0 or
another on-state. Thus lspci cannot be used to diagnose power consumption
issues for devices that can enter D3cold or to ensure that devices properly
enter D3cold at all.
Add a new sysfs device attribute for the PCI power state, showing the
current power state as seen by the kernel.
