Symptoms:
	PHKL_23418:
	(SR: 8606162269   CR: JAGad31585)
	Mount(2) system call fails, when it is invoked with
	NULL dataptr and 0 datalen.

	(SR: 8606178149   CR: JAGad47376)
	A corrupted file system could be mounted, and an fsck
	on the filesystem thereafter fails with the following
	error messages,

	# fsck -F vxfs /dev/vgtest/lvol4
	log replay in progress
	a full file system check is required

	# fsck -F vxfs -o full /dev/vgtest/lvol4
	log replay in progress
	pass0 - checking structural files
	pass1 - checking inode sanity and blocks
	fileset 999 inode 2 has invalid attributes clear? (ynq)y
	root inode for fileset 999 is invalid - terminating fileset

	This problem was introduced by PHKL_15244.

Defect Description:
	PHKL_23418:
	(SR: 8606162269   CR: JAGad31585)
	VxFS mount(2) was expecting a dataptr and non-zero datalen.

	Resolution:
	Changed VxFS mount(2) to accept NULL dataptr and 0 datalen.

	(SR: 8606178149   CR: JAGad47376)
	A function invoked with less number of arguments than
	required allowed mounting corrupted file systems.

	Resolution:
	Invoke the function with correct number of arguments.
