compat_fetch_robust

函数名称：Fetch a robust-list pointer. Bit 0 signals PI futexes:

函数原型：static inline int compat_fetch_robust_entry(compat_uptr_t *uentry, struct robust_list __user **entry, compat_uptr_t __user *head, unsigned int *pi)

返回类型：int

参数：

类型	参数	名称
compat_uptr_t *	uentry
struct robust_list __user **	entry
compat_uptr_t __user *	head
unsigned int *	pi

3954

如果Careful: we have to cast the result to the type of the pointer* for sign reasons( * uentry, head)则返回:负EFAULT

3957

entry等于A pointer passed in from user mode. This should not* be used for syscall parameters, just declare them* as pointers because the syscall entry code will have* appropriately converted them already.

3958

pi等于uentry按位与1

3960

返回:0
