函数名称:_unnecessary_pages - Release preallocated pages not needed for the image.
函数原型:static unsigned long free_unnecessary_pages(void)
返回类型:unsigned long
参数:无
1605 | to_free_normal等于Numbers of normal and highmem page frames allocated for hibernation image* before suspending devices.减save |
1606 | save等于0 |
1607 | 否则 |
1608 | to_free_normal等于0 |
1611 | save加等于count_highmem_pages() |
1614 | 否则 |
1615 | to_free_highmem等于0 |
1616 | save减等于Numbers of normal and highmem page frames allocated for hibernation image* before suspending devices. |
1617 | 如果to_free_normal大于save则to_free_normal减等于save |
1619 | 否则to_free_normal等于0 |
1626 | 当to_free_normal大于0或to_free_highmem大于0循环 |
1628 | page等于pfn_to_page(pfn) |
1630 | 如果PageHighMem(page)则 |
1631 | 如果非to_free_highmem则继续下一循环 |
1633 | to_free_highmem自减 |
1635 | 否则 |
1636 | 如果非to_free_normal则继续下一循环 |
1638 | to_free_normal自减 |
1643 | swsusp_unset_page_free(page) |
