函数名称:__gup_longterm_locked() is a wrapper for __get_user_pages_locked which* allows us to process the FOLL_LONGTERM flag.
函数原型:static long __gup_longterm_locked(struct task_struct *tsk, struct mm_struct *mm, unsigned long start, unsigned long nr_pages, struct page **pages, struct vm_area_struct **vmas, unsigned int gup_flags)
返回类型:long
参数:
类型 | 参数 | 名称 |
---|---|---|
struct task_struct * | tsk | |
struct mm_struct * | mm | |
unsigned long | start | |
unsigned long | nr_pages | |
struct page ** | pages | |
struct vm_area_struct ** | vmas | |
unsigned int | gup_flags |
1559 | flags等于0 |
1566 | 如果非vmas_tmp则 |
1573 | flags等于memalloc_nocma_save() |
1580 | memalloc_nocma_restore(flags) |
1595 | out : |
1598 | 返回:rc |
名称 | 描述 |
---|---|
get_user_pages | This is the same as get_user_pages_remote(), just with a* less-flexible calling convention where we assume that the task* and mm being operated on are the current task's and don't allow* passing of a locked parameter. We also obviously don't pass |
