Type:bool

Parameter:

Type	Parameter	Name
struct vm_area_struct *	vma

**Caller**
Name	Describe
dup_mmap
__get_user_pages	__get_user_pages() - pin user pages in memory@tsk: task_struct of target task@mm: mm_struct of target mm@start: starting user address@nr_pages: number of pages from start to pin*@gup_flags: flags modifying pin behaviour
free_pgtables
copy_page_range
unmap_single_vma
handle_mm_fault	By the time we get here, we already hold the mm semaphore* The mmap_sem may have been released depending on flags and our* return value. See filemap_fault() and __lock_page_or_retry().
mlock_fixup	mlock_fixup - handle mlock[all]/munlock[all] requests.* Filters out "special" vmas -- VM_LOCKED never gets set for these, and* munlock is a no-op. However, for some special vmas, we go ahead and* populate the ptes.
mmap_region
mm_take_all_locks	This operation locks against the VM for all pte/vma/mm related* operations that could ever happen on a certain mm. This includes* vmtruncate, try_to_unmap, and all page faults.* The caller must take the mmap_sem in write mode before calling
change_protection
vma_to_resize
__walk_page_range
madvise_behavior	We can potentially split a vm area into separate* areas, each area with its own behavior.
vma_resv_map
set_vma_resv_map
set_vma_resv_flags
is_vma_resv_set
reset_vma_resv_huge_pages	Reset counters to 0 and clear all HPAGE_RESV_* flags
__unmap_hugepage_range
queue_pages_test_walk
__mcopy_atomic_hugetlb	__mcopy_atomic processing for HUGETLB vmas. Note that this routine is* called with mmap_sem held, it will release mmap_sem before returning.
__mcopy_atomic
handle_userfault	The locking rules involved in returning VM_FAULT_RETRY depending on* FAULT_FLAG_ALLOW_RETRY, FAULT_FLAG_RETRY_NOWAIT and* FAULT_FLAG_KILLABLE are not straightforward
vma_can_userfault
userfaultfd_register
userfaultfd_unregister
