2024-09-06libfs: fix get_stashed_dentry()Christian Brauner
get_stashed_dentry() tries to optimistically retrieve a stashed dentry from a provided location. It needs to ensure to hold rcu lock before it dereference the stashed location to prevent UAF issues. Use rcu_dereference() instead of READ_ONCE() it's effectively equivalent with some lockdep bells and whistles and it communicates clearly that this expects rcu protection.

2024-09-06ice: add basic devlink subfunctions supportPiotr Raczynski
Implement devlink port handlers responsible for ethernet type devlink subfunctions. Create subfunction devlink port and setup all resources needed for a subfunction netdev to operate. Configure new VSI for each new subfunction, initialize and configure interrupts and Tx/Rx resources. Set correct MAC filters and create new netdev. For now, subfunction is limited to only one Tx/Rx queue pair. Only allocate new subfunction VSI with devlink port new command. Allocate and free subfunction MSIX interrupt vectors using new API calls with pci_msix_alloc_irq_at and pci_msix_free_irq. Support both automatic and manual subfunction numbers. If no subfunction number is provided, use xa_alloc to pick a number automatically. This will find the first free index and use that as the number. This reduces burden on users in the simple case where a specific number is not required. It may also be slightly faster to check that a number exists since xarray lookup should be faster than a linear scan of the dyn_ports xarray.

2024-09-06md: Add new_level sysfs interfaceXiao Ni
Now reshape supports two ways: with backup file or without backup file. For the situation without backup file, it needs to change data offset. It doesn't need systemd service mdadm-grow-continue. So it can finish the reshape job in one process environment. It can know the new level from mdadm --grow command and can change to new level after reshape finishes. For the situation with backup file, it needs systemd service mdadm-grow-continue to monitor reshape progress. So there are two process envolved. One is mdadm --grow command whick kicks off reshape and wakes up mdadm-grow-continue service. The second process is the service, which doesn't know the new level from the first process. In kernel space mddev->new_level is used to record the new level when doing reshape. This patch adds a new interface to help mdadm update new_level and sync it to metadata. Then mdadm-grow-continue can read the right new_level. Commit log revised by Song Liu. Please refer to the link for more details.

2024-09-06selftests:resctrl: Fix build failure on archs without __cpuid_count()Shuah Khan
When resctrl is built on architectures without __cpuid_count() support, build fails. resctrl uses __cpuid_count() defined in kselftest.h. Even though the problem is seen while building resctrl on aarch64, this error can be seen on any platform that doesn't support CPUID. CPUID is a x86/x86-64 feature and code paths with CPUID asm commands will fail to build on all other architectures. All others tests call __cpuid_count() do so from x86/x86_64 code paths when _i386__ or __x86_64__ are defined. resctrl is an exception. Fix the problem by defining __cpuid_count() only when __i386__ or __x86_64__ are defined in kselftest.h and changing resctrl to call __cpuid_count() only when __i386__ or __x86_64__ are defined.

The zram_table_entry::flags member is of type long and uses 8 bytes on a 64bit architecture. With a PAGE_SIZE of 256KiB we have PAGE_SHIFT of 18 which in turn leads to __NR_ZRAM_PAGEFLAGS = 27. This still fits in an ordinary integer. By reducing the size of `flags' to four bytes, the size of the struct goes back to 16 bytes. The padding between the lock and ac_time (if enabled) is also gone. Make zram_table_entry::flags an unsigned int and update the build test to reflect the change.

2024-09-06nbd: correct the maximum value for discard sectorsWouter Verhelst
The version of the NBD protocol implemented by the kernel driver currently has a 32 bit field for length values. As the NBD protocol uses bytes as a unit of length, length values larger than 2^32 bytes cannot be expressed. Update the max_hw_discard_sectors field to match that.

2024-09-06MAINTAINERS: Move the BFQ io scheduler to Odd Fixes stateYu Kuai
BFQ has been lacking active maintenance for approximately two years, and it was recently transitioned to the Orphan state. However, there are still many users, I have decided to step forward and assume the role of maintainer to ensure continued support and development. While I may not be the one with the most extensive knowledge of BFQ's internals, I have been actively involved in its development since 2021. Moreover, our team continues to rigorously test BFQ in downstream kernels, ensuring it's stability and performance. Despite my confidence to maintain BFQ, I believe it is prudent to classify its state as "Odd Fixes" to accurately reflect my relatively new position as the maintainer. By assuming this responsibility, I am committed to providing the necessary support and addressing any issues that may arise with BFQ. As time progresses, we will reassess the situation and determine the appropriate state.

2024-09-06platform/x86:intel/pmc: Enable the ACPI PM Timer to be turned off when suspendedMarek Maslanka
Allow to disable ACPI PM Timer on suspend and enable on resume. A disabled timer helps optimise power consumption when the system is suspended. On resume the timer is only reactivated if it was activated prior to suspend, so unless the ACPI PM timer is enabled in the BIOS, this won't change anything. The ACPI PM timer is used by Intel's iTCO/wdat_wdt watchdog to drive the watchdog, so it doesn't need to run during suspend.
