digging into kernel-user space copying and i can see that, depending
on whether i'm running sparse, i'll get __chk_user_ptr() defined in
one of two ways in <linux/compiler.h>:
#ifdef __CHECKER__
...
extern void __chk_user_ptr(const volatile void __user *);
extern void __chk_io_ptr(const volatile void __iomem *);
#else
...
# define __chk_user_ptr(x) (void)0
# define __chk_io_ptr(x) (void)0
#endif
but if i define __CHECKER__, where *is* the external definition of
those two routines? i've grepped and can't see them. thanks.
