  log: |
    Locking a layer vnode is racy as it may become reclaimed before
    calling the operation on the lower vnode.

    Replace vi_lock with a rw_obj and change layered file systems
    to share the lock with the lower vnode.

    Layered file systems now use genfs_lock()/_unlock/_islocked().
