Defect Description:
	PHKL_18624:
	Ported HP-UX patch PHKL_14765 for VVOS.

	Resolution:
	Ported HP-UX patch PHKL_14765.

	Based on PHKL_14765:
	None

	Based on PHKL_13441:
	The system PANICs when it can not find a file system block.
	This PANIC occurs in alloccg because of a NULL value being
	used as a valid block number.  The system attempts to
	allocate a block whose value is NULL and so PANICs.
