函数名称：'pteval' can come from a PTE, PMD or PUD. We only check* _PAGE_PRESENT, _PAGE_USER, and _PAGE_RW in here which are the* same value on all 3 types.
函数原型：static inline bool __pte_access_permitted(unsigned long pteval, bool write)
返回类型：bool
参数：
| 类型 | 参数 | 名称 |
|---|---|---|
| unsigned long | pteval | |
| bool | write |
| 1429 | need_pte_bits等于_PAGE_PRESENT按位或_PAGE_USER |
| 1431 | 如果write则need_pte_bits或等于_PAGE_RW |
| 1434 | 如果pteval按位与need_pte_bits的值不等于need_pte_bits则返回:0 |
| 1437 | 返回:__pkru_allows_pkey(pte_flags_pkey(pteval), write) |
