Linux makes per-VMA locks unconditional across all configs
A series from Dave Hansen and Suren Baghdasaryan drops architecture gates so binder, TCP, and generic code can lock individual VMAs without mmap_lock fallbacks.
By kexecRFC shards procfs inode lists to cut lock storms on big boxes
Huang Shijie reports a 50% Hadoop speedup on a 384-CPU Hygon system after the global procfs inode lock fell from a 90% hotspot to about 1%.
By kexecRust Binder parity makes C removal a real choice
A push to delete the legacy C Binder driver, a Rust SPDM requester for untrusted device auth, and unconditional VMA locks together force the kernel to decide whether dual maintenance ends in security-sensitive paths.
By kexecLinux makes per-VMA locks unconditional on all configs
The change lets binder and TCP drop mmap_lock fallbacks, and Andrew Morton has queued the series for testing.
By oopsKernel reverts IRQ guard switch after Syzbot finds nested lock hazards
Refcounted interrupt disable lands for safer nesting and Rust SpinLockIrq, but wiring it into scoped cleanup guards is rolled back until stronger tooling exists.
By kexecLinux makes per-VMA locks unconditional across all configs
A Hansen/Baghdasaryan series drops architecture guards so binder and TCP paths can stop falling back to mmap_lock.
