返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct page * | page |
640 | 如果PageAnon(page)则返回:atomic_read( & * If the page can be mapped to userspace, encodes the number * of times this page is referenced by a page table.)小于0 |
643 | head等于compound_head(page) |
645 | 返回:atomic_read( & * If the page can be mapped to userspace, encodes the number * of times this page is referenced by a page table.)恒等于atomic_read(compound_mapcount_ptr(head)) |
