1077 | 如果TestSetPageHWPoison(head)则 |
1083 | num_poisoned_pages_inc() |
1090 | 如果PageHWPoison(head)则 |
1091 | 如果hwpoison_filter(p)且TestClearPageHWPoison(p)或p不等于head且TestSetPageHWPoison(head)则 |
1093 | num_poisoned_pages_dec() |
1095 | 返回:0 |
1101 | 返回:0 |
1105 | page_flags等于体系结构无关页的属性 |
1107 | 如果非PageHWPoison(head)则 |
1124 | 如果huge_page_size(page_hstate(head))大于PMD_SIZE则 |
1127 | 转到:out |
1133 | 转到:out |
1136 | res等于identify_page_state(pfn, p, page_flags) |
