* feat(sched): support reset-on-fork scheduler semantics Align the legacy sched_getparam and sched_getscheduler interfaces with Linux by using the four-byte kernel ABI, signed TID lookup, unrestricted query semantics, consistent policy snapshots, and strict RT priority conversion. Implement the SCHED_OTHER reset-on-fork fast path for sched_setscheduler with Linux-compatible validation ordering, owner and CAP_SYS_NICE checks, protected-flag clearing rules, and per-task fork and clone reset behavior. Keep unsupported class transitions explicit and outside the runqueue mutation path. Tighten the internal FIFO priority endpoint, update the virtio block worker priority, and add dunitest coverage for ABI boundaries, errno ordering, other-TID access, credentials, fork, clone, and task lifetime behavior.

DragonOS allocated the root loopback index from a global counter shared with device initcalls, so link-order changes could place lo after enough test interfaces that a bounded SIOCGIFCONF result omitted it. Define the loopback index invariant once, construct loopback devices with that index, and start dynamic root-device allocation at 2. Remove the allocation-based loopback constructor and strengthen the ioctl dunitest to assert the Linux ABI value. This restores all 41 ioctl_test cases while preserving normal interface enumeration semantics.

VethInterface::mac previously reacquired that lock, deadlocking the NAPI worker and every later user of the interface. Keep the immutable veth MAC address in the interface metadata and make mac() a lock-free read. Document the data-path locking contract and extend the SO_BINDTODEVICE regression to verify the interface remains usable after ingress processing.
