block/compat_ioctl.c:85:11: expected unsigned long *[noderef] <asn:1>p
block/compat_ioctl.c:85:11: got void [noderef] <asn:1>*
block/compat_ioctl.c:91:21: warning: incorrect type in argument 1 (different address spaces)
block/compat_ioctl.c:91:21: expected void const volatile [noderef] <asn:1>*<noident>
block/compat_ioctl.c:91:21: got unsigned long *[noderef] <asn:1>p
block/compat_ioctl.c:87:53: warning: dereference of noderef expression
block/compat_ioctl.c:91:21: warning: dereference of noderef expression
