ALLOC_VM_AREA(9)                    Memory Management in Linux                   ALLOC_VM_AREA(9)



NAME
       alloc_vm_area - allocate a range of kernel address space

SYNOPSIS
       struct vm_struct * alloc_vm_area(size_t size, pte_t ** ptes);

ARGUMENTS
       size
           size of the area

       ptes
           returns the PTEs for the address space

RETURN
       NULL on failure, vm_struct on success

       This function reserves a range of kernel address space, and allocates pagetables to map
       that range. No actual mappings are created.

       If ptes is non-NULL, pointers to the PTEs (in init_mm) allocated for the VM area are
       returned.
