compat_fetch_robust

Name:Fetch a robust-list pointer. Bit 0 signals PI futexes:

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

Type:int

Parameter:

Type	Parameter	Name
compat_uptr_t *	uentry
struct robust_list __user **	entry
compat_uptr_t __user *	head
unsigned int *	pi

3954

If Get a simple variable from user space( * uentry, head) Then Return -EFAULT

3957

entry = 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 = uentry & 1

3960

Return 0
