Spawn kernel_init (PID 1) via kernel_clone() directly instead of user_mode_thread(), without CLONE_FS. This gives PID 1 its own private copy of init_task's fs_struct rather than sharing it. This is a prerequisite for isolating kthreads in nullfs: when init_task's fs is later pointed at nullfs, PID 1 must not share it or init_userspace_fs() would modify init_task's fs as well, defeating the isolation. At this stage PID 1 still gets rootfs (a private copy rather than a shared reference), so there is no functional change.
