- * access_ok - Checks if a user space pointer is valid

- * @size: Size of block to check
- *
- * Context: User context only. This function may sleep if pagefaults are
- * enabled.
- *
- * Checks if a pointer to a block of memory in user space is valid.
- *
- * Note that, depending on architecture, this function probably just
- * checks that the pointer is in the user space range - after calling
- * this function, memory access functions may still return -EFAULT.
- *
- * Return: true (nonzero) if the memory block may be valid, false (zero)
- * if it is definitely invalid.
- *
- * This should not be x86-specific. The only odd things out here is
- * the WARN_ON_IN_IRQ(), which doesn't exist in the generic version.
