函数逻辑报告

函数名称：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.

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

返回类型：pmd_t

参数：
