Path Name: /hp-ux_patches/s700_800/10.X/PHSS_21604

Symptoms:
	PHSS_21604:
	1) Application record with wildcard causes system daemons,
	such as vhand, to be moved into the PRM group specified by
	the application record.
	2) prmmonitor <logical_volume_group> prints garbage if the
	PRM disk resource manager is not enabled and at least one
	other PRM resource manager is enabled.

	PHSS_20672:
	1) Writing to mmap files causes PRM to think the
	system is paging.
	2) prmmonitor -s doesn't display PRM_SYS group.
	3) prmconfig and xprm will core dump if application
	record wildcard matches a zero-length file which has
	execute permission.

Defect Description:
	PHSS_21604:
	1) prmconfig was treating the wildcard pathname itself as
	a filename.  Since the wildcard pathname doesn't exist, it
	maps to file id -1.  Since system daemons like vhand have
	no path or backing file, their file id is also -1.
	2) prmmonitor tried to print resource management statistics
	for a device even if resource management for the device was
	not enabled.  Now, statistics are gathered only if resource
	management for the device is enabled.

	PHSS_20672:
	1) The kernel variable that PRM uses to monitor page-outs
	is incremented when processes write to mmap files.  This
	can fool PRM into thinking that the system is out of free
	memory and paging.
	2) prmmonitor -s was not displaying the PRM_SYS group.
	3) prmconfig and xprm use the same library, libprmext,
	to process application records.  The libprmext library
	contained code which would dereference a null pointer
	if an application record wildcard matched a zero-length
	file which had execute permission.
