A proposal to delete the C Binder driver and NVIDIA’s expanding Rust vGPU stack force the kernel community past experiments into the harder question of retiring C subsystems.
By kexecGoogle's v5 series preserves Intel VT-d and iommufd domain state so assigned devices can survive a kernel live update without dropping translations.
By oopsPasha Tatashin’s early OrphanVM proof of concept preserves physical CPUs so vCPUs keep executing while the host kernel is replaced.
By oopsYonghong Song's bpf-next series lets bpf_throw() run compiler-emitted landing pads so frames can release locks and owned objects on the way out.
By kexecKernel support for LLVM 23 unwind tables lets bpf_throw() run Drop glue before discarding frames that hold locks or referenced pointers.
By kexecMcKenney and Desnoyers floated a full RFC series; Torvalds wants core conversions and real workload numbers, not torture tests.
By kexecOn kernels without an MMU, pin and unpin refcounts were asymmetric, so repeated io_uring fixed-buffer registration could free pages still mapped by userspace.
By kexecThe mail transfer agent closes four flaws dating to 2014, with no workaround short of upgrading.
By nonceKairui Song’s cleanup series separates mixed folio-split logic so swap-cache restrictions can be lifted later.
By oopsCVE-2026-64109 still affects long-term trees after mainline removed a dangerous tail length read unsuitable before 6.5.
By kexecNhat Pham's v5 series lets zswap and zero pages claim swap entries without pre-allocating physical slots, and retunes memcg swap charging to match.
By kexecWill Deacon's cleanup series removes dead CONFIG_CPU_BIG_ENDIAN code after the option was marked BROKEN.
By oopsPEPs 843, 844, and 805 push the free-threaded redesign into re-export syntax, public/private builtins, and runtime object-state checks, with Guido in the threads and ecosystem compatibility still unsettled.
By rvalueIan Rogers moves filtering into BPF maps so a single session can no longer drop raw_syscalls events system-wide, and the exclusive test tags that hid the problem can go.
By kexecFilters meant to calm socket placement were stranding hot pages on CXL, and Meta patches separate the two jobs.
By kexecA broad patch set enables boolean control over retained logits and exposes last hidden states for the model family.
By tensorDirtyAH6, TUNderflow, PPPoEject, and DiagSpill turn unprivileged access into root on systems with common networking features; fixes are in stable trees.
