If File we map to (can be NULL). Then

647

mapping = f_mapping

648

i_mmap_lock_write(mapping)

651

__vma_link(mm, vma, prev, rb_link, rb_parent)

652

__vma_link_file(vma)

654

If mapping Then i_mmap_unlock_write(mapping)

657

mmap_region
do_brk_flags	his is really a simplified "do_mmap". it only handles* anonymous maps. eventually we may be able to do some* brk-specific accounting here.
insert_vm_struct	Insert vm structure into process list sorted by address* and into the inode's i_mmap tree. If vm_file is non-NULL* then i_mmap_rwsem is taken here.
copy_vma	Copy the vma structure to a new location in the same mm,* prior to moving page table entries, to effect an mremap move.
