Type:int

Parameter:

Type	Parameter	Name
struct anon_vma *	anon_vma1
struct anon_vma *	anon_vma2
struct vm_area_struct *	vma

If ( Not anon_vma1 || Not anon_vma2 ) && ( Not vma || list_is_singular - tests whether a list has just one entry.*@head: the list to test.) Then Return 1

1019

Return anon_vma1 == anon_vma2

**Caller**
Name	Describe
can_vma_merge_before	Return true if we can merge this (vm_flags,anon_vma,file,vm_pgoff)* in front of (at a lower virtual address and file offset than) the vma.* We cannot merge two vmas if they have differently assigned (non-NULL)
can_vma_merge_after	Return true if we can merge this (vm_flags,anon_vma,file,vm_pgoff)* beyond (at a higher virtual address and file offset than) the vma.* We cannot merge two vmas if they have differently assigned (non-NULL)
vma_merge	Given a mapping request (addr,end,vm_flags,file,pgoff), figure out* whether that can be merged with its predecessor or its successor
