函数名称:Common helper functions. Never use with __GFP_HIGHMEM because the returned* address cannot represent highmem pages. Use alloc_pages and then kmap if* you need to access high mem.
函数原型:unsigned long __get_free_pages(gfp_t gfp_mask, unsigned int order)
返回类型:unsigned long
参数:
类型 | 参数 | 名称 |
---|---|---|
gfp_t | gfp_mask | |
unsigned int | order |
4775 | page等于alloc_pages(gfp_mask & ~__GFP_HIGHMEM, order) |
4776 | 如果非page则返回:0 |
4778 | 返回:page_address(page) |
