Symptoms:
	PHKL_19202:
	SR: 5003461947 DTS: JAGab17359
	HPUX 11.0 (32 and 64) panics after extending the root
	filesystem using fsadm.

Defect Description:
	PHKL_19202:
	SR: 5003461947 DTS: JAGab17359
	HPUX 11.0 (32 and 64) panics after extending the root
	filesystem using fsadm. The first parameter (vpp) in
	devtovp_open() is used improperly and that causes a
	panic. It is correctly passed in as a "struct vnode **",
	but not dereferenced properly before using it in the
	"major()" macro which expects a "dev_t".

	Here is a typical stack trace:

	panic+0x14
	report_trap_or_int_and_panic+0x4c
	trap+0x7a4
	$RDB_trap_patch+0x38
	devtovp_open+0x104
	vx_resize+0x6d0
	vx_aioctl_fullfs+0x114
	vx_aioctl_common+0x33c
	vx_aioctl+0x80
	vx_ioctl+0xbc
	vno_ioctl+0x8c
	ioctl+0x138
	syscall+0x1c8
	$syscallrtn+0x0

	Resolution:
	The first parameter (vpp) in devtovp_open() is
	dereferenced properly before using it in the
	"major()" macro which expects a dev_t.
