返回类型:long
参数:
类型 | 参数 | 名称 |
---|---|---|
unsigned long | addr | |
unsigned long | pages | |
unsigned char * | vec |
214 | 如果非vma或addr小于Our start address within vm_mm. 则返回:负ENOMEM |
216 | end等于两数取小(The first byte after our end addresswithin vm_mm. , addr + (pages << PAGE_SHIFT determines the page size )) |
217 | 如果非can_do_mincore(vma)则 |
222 | err等于walk_page_range(The address space we belong to. , addr, end, & mincore_walk_ops, vec) |
225 | 返回:end减addr右移PAGE_SHIFT determines the page size 位 |
