    mm, vmalloc: iterate vmap_area_list in get_vmalloc_info() · f98782dd
    Joonsoo Kim authored
    This patch is a preparatory step for removing vmlist entirely.  For
    above purpose, we change iterating a vmap_list codes to iterating a
    vmap_area_list.  It is somewhat trivial change, but just one thing
    should be noticed.
    vmlist is lack of information about some areas in vmalloc address space.
    For example, vm_map_ram() allocate area in vmalloc address space, but it
    doesn't make a link with vmlist.  To provide full information about
    vmalloc address space is better idea, so we don't use va->vm and use
    vmap_area directly.  This makes get_vmalloc_info() more precise.
