| Subject: mm/vmalloc.c: change void* into explict vm_struct* |
| |
| From: Minchan Kim <minchan@kernel.org> |
| |
| commit db1aecafef58b5dda39c4228debe2c845e4a27ab upstream. |
| |
| vmap_area->private is void* but we don't use the field for various purpose |
| but use only for vm_struct. So change it to a vm_struct* with naming to |
| improve for readability and type checking. |
