Thu, 19 Mar 2026 01:20:18 +0100

init/Kconfig: Require a release version of clang-22 for CC_HAS_COUNTED_BY_PTRCommit 150a04d817d8 ("compiler_types.h: Attributes: Add __counted_by_ptrmacro") used Clang 22.0.0 as a minimum supported version for__counted_by_ptr, which made sense while 22.0.0 was the version ofLLVM's main branch to allow developers to easily test and develop usesof __counted_by_ptr in their code. However, __counted_by_ptr requires achange [1] merged towards the end of the 22 development cycle to avoiderrors when applied to void pointers.

init/Kconfig: Adjust fixed clang version for __builtin_counted_by_refCommit d39a1d7486d9 ("compiler_types: Disable __builtin_counted_by_reffor Clang") used 22.0.0 as the fixed version for a compiler crash butthe fix was only merged in main (23.0.0) and release/22.x (22.1.0). Withthe current fixed version number, prerelease or Android LLVM 22 buildswill still be able to hit the compiler crash when building the kernel.This can be particularly disruptive when bisecting LLVM.Use 21.1.0 as the fixed version number to ensure the fix for this crashis always present.Fixes: d39a1d7486d9 ("compiler_types: Disable __builtin_counted_by_ref for Clang")Signed-off-by: Nathan Chancellor Link: https://patch.msgid.link/20260223-fix-clang-version-builtin-counted-by-ref-v1-1-3ea478a24f0a@kernel.orgSigned-off-by: Kees Cook List of files: /linux/init/Kconfig

Merge tag 'kvm-x86-pmu-6.20' of https://github.com/kvm-x86/linux into HEADKVM mediated PMU support for 6.20Add support for mediated PMUs, where KVM gives the guest full ownership of PMUhardware (contexted switched around the fastpath run loop) and allows directaccess to data MSRs and PMCs (restricted by the vPMU model), but interceptsaccess to control registers, e.g. to enforce event filtering and to prevent theguest from profiling sensitive host state.To keep overall complexity reasonable, mediated PMU usage is all or nothingfor a given instance of KVM (controlled via module param). The Mediated PMUis disabled default, partly to maintain backwards compatilibity for existingsetup, partly because there are tradeoffs when running with a mediated PMU thatmay be non-starters for some use cases, e.g. the host loses the ability toprofile guests with mediated PMUs, the fastpath run loop is also a blind spot,entry/exit transitions are more expensive, etc.Versus the emulated PMU, where KVM is "just another perf user", the mediatedPMU delivers more accurate profiling and monitoring (no risk of contention andthus dropped events), with significantly less overhead (fewer exits and fasteremulation/programming of event selectors) E.g. when running Specint-2017 ona single-socket Sapphire Rapids with 56 cores and no-SMT, and using perf fromwithin the guest: Perf command: a. basic-sampling: perf record -F 1000 -e 6-instructions -a --overwrite b. multiplex-sampling: perf record -F 1000 -e 10-instructions -a --overwrite Guest performance overhead: --------------------------------------------------------------------------- | Test case | emulated vPMU | all passthrough | passthrough with | | | | | event filters | --------------------------------------------------------------------------- | basic-sampling | 33.62% | 4.24% | 6.21% | --------------------------------------------------------------------------- | multiplex-sampling | 79.32% | 7.34% | 10.45% | --------------------------------------------------------------------------- List of files: /linux/init/Kconfig

Merge tag 'kthread-for-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticksPull kthread updates from Frederic Weisbecker: "The kthread code provides an infrastructure which manages the preferred affinity of unbound kthreads (node or custom cpumask) against housekeeping (CPU isolation) constraints and CPU hotplug events. One crucial missing piece is the handling of cpuset: when an isolated partition is created, deleted, or its CPUs updated, all the unbound kthreads in the top cpuset become indifferently affine to _all_ the non-isolated CPUs, possibly breaking their preferred affinity along the way. Solve this with performing the kthreads affinity update from cpuset to the kthreads consolidated relevant code instead so that preferred affinities are honoured and applied against the updated cpuset isolated partitions. The dispatch of the new isolated cpumasks to timers, workqueues and kthreads is performed by housekeeping, as per the nice Tejun's suggestion. As a welcome side effect, HK_TYPE_DOMAIN then integrates both the set from boot defined domain isolation (through isolcpus=) and cpuset isolated partitions. Housekeeping cpumasks are now modifiable with a specific RCU based synchronization. A big step toward making nohz_full= also mutable through cpuset in the future"* tag 'kthread-for-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks: (33 commits) doc: Add housekeeping documentation kthread: Document kthread_affine_preferred() kthread: Comment on the purpose and placement of kthread_affine_node() call kthread: Honour kthreads preferred affinity after cpuset changes sched/arm64: Move fallback task cpumask to HK_TYPE_DOMAIN sched: Switch the fallback task allowed cpumask to HK_TYPE_DOMAIN kthread: Rely on HK_TYPE_DOMAIN for preferred affinity management kthread: Include kthreadd to the managed affinity list kthread: Include unbound kthreads in the managed affinity list kthread: Refine naming of affinity related fields PCI: Remove superfluous HK_TYPE_WQ check sched/isolation: Remove HK_TYPE_TICK test from cpu_is_isolated() cpuset: Remove cpuset_cpu_is_isolated() timers/migration: Remove superfluous cpuset isolation test cpuset: Propagate cpuset isolation update to timers through housekeeping cpuset: Propagate cpuset isolation update to workqueue through housekeeping PCI: Flush PCI probe workqueue on cpuset isolated partition change sched/isolation: Flush vmstat workqueues on cpuset isolated partition change sched/isolation: Flush memcg workqueues on cpuset isolated partition change cpuset: Update HK_TYPE_DOMAIN cpumask from cpuset ...

Merge tag 'vfs-7.0-rc1.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfsPull misc vfs updates from Christian Brauner: "This contains a mix of VFS cleanups, performance improvements, API fixes, documentation, and a deprecation notice. Scalability and performance: - Rework pid allocation to only take pidmap_lock once instead of twice during alloc_pid(), improving thread creation/teardown throughput by 10-16% depending on false-sharing luck. Pad the namespace refcount to reduce false-sharing - Track file lock presence via a flag in ->i_opflags instead of reading ->i_flctx, avoiding false-sharing with ->i_readcount on open/close hot paths. Measured 4-16% improvement on 24-core open-in-a-loop benchmarks - Use a consume fence in locks_inode_context() to match the store-release/load-consume idiom, eliminating a hardware fence on some architectures - Annotate cdev_lock with __cacheline_aligned_in_smp to prevent false-sharing - Remove a redundant DCACHE_MANAGED_DENTRY check in __follow_mount_rcu() that never fires since the caller already verifies it, eliminating a 100% mispredicted branch - Fix a 100% mispredicted likely() in devcgroup_inode_permission() that became wrong after a prior code reorder Bug fixes and correctness: - Make insert_inode_locked() wait for inode destruction instead of skipping, fixing a corner case where two matching inodes could exist in the hash - Move f_mode initialization before file_ref_init() in alloc_file() to respect the SLAB_TYPESAFE_BY_RCU ordering contract - Add a WARN_ON_ONCE guard in try_to_free_buffers() for folios with no buffers attached, preventing a null pointer dereference when AS_RELEASE_ALWAYS is set but no release_folio op exists - Fix select restart_block to store end_time as timespec64, avoiding truncation of tv_sec on 32-bit architectures - Make dump_inode() use get_kernel_nofault() to safely access inode and superblock fields, matching the dump_mapping() pattern API modernization: - Make posix_acl_to_xattr() allocate the buffer internally since every single caller was doing it anyway. Reduces boilerplate and unnecessary error checking across ~15 filesystems - Replace deprecated simple_strtoul() with kstrtoul() for the ihash_entries, dhash_entries, mhash_entries, and mphash_entries boot parameters, adding proper error handling - Convert chardev code to use guard(mutex) and __free(kfree) cleanup patterns - Replace min_t() with min() or umin() in VFS code to avoid silently truncating unsigned long to unsigned int - Gate LOOKUP_RCU assertions behind CONFIG_DEBUG_VFS since callers already check the flag Deprecation: - Begin deprecating legacy BSD process accounting (acct(2)). The interface has numerous footguns and better alternatives exist (eBPF) Documentation: - Fix and complete kernel-doc for struct export_operations, removing duplicated documentation between ReST and source - Fix kernel-doc warnings for __start_dirop() and ilookup5_nowait() Testing: - Add a kunit test for initramfs cpio handling of entries with filesize > PATH_MAX Misc: - Add missing include in fs_struct.c"* tag 'vfs-7.0-rc1.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (28 commits) posix_acl: make posix_acl_to_xattr() alloc the buffer fs: make insert_inode_locked() wait for inode destruction initramfs_test: kunit test for cpio.filesize > PATH_MAX fs: improve dump_inode() to safely access inode fields fs: add for 'init_fs' docs: exportfs: Use source code struct documentation fs: move initializing f_mode before file_ref_init() exportfs: Complete kernel-doc for struct export_operations exportfs: Mark struct export_operations functions at kernel-doc exportfs: Fix kernel-doc output for get_name() acct(2): begin the deprecation of legacy BSD process accounting device_cgroup: remove branch hint after code refactor VFS: fix __start_dirop() kernel-doc warnings fs: Describe @isnew parameter in ilookup5_nowait() fs/namei: Remove redundant DCACHE_MANAGED_DENTRY check in __follow_mount_rcu fs: only assert on LOOKUP_RCU when built with CONFIG_DEBUG_VFS select: store end_time as timespec64 in restart block chardev: Switch to guard(mutex) and __free(kfree) namespace: Replace simple_strtoul with kstrtoul to parse boot params dcache: Replace simple_strtoul with kstrtoul in set_dhash_entries ...
