Subject: [PATCH 31/86] mm/vmalloc.c: change void* into explict vm_struct*
|
|
|
|
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.
