Name:This is an implementation of pmdp_establish() that is only suitable for an* architecture that doesn't have hardware dirty/accessed bits. In this case we* can't race with CPU which sets these bits and non-atomic aproach is fine.

Proto:static inline pmd_t generic_pmdp_establish(struct vm_area_struct *vma, unsigned long address, pmd_t *pmdp, pmd_t pmd)

Type:pmd_t

Parameter:

TypeParameterName
struct vm_area_struct *vma
unsigned longaddress
pmd_t *pmdp
pmd_tpmd
321  old_pmd = pmdp
322  set_pmd_at(The address space we belong to. , address, pmdp, pmd)
323  Return old_pmd
