Symptoms:
	PHCO_19623:
	Recompile needed due to enhanced libc routine.

	PHCO_16581:
	mount_hfs(1M) returns an error when quotactl() fails, even
	though the quotactl() failure only gives a warning.

Defect Description:
	PHCO_19623:
	Enhancements were made to libc routines to support VxFS
	version 4.  Therefore, mount_hfs needs to be recompiled,
	since it calls one of the libc routines that changed.

	For full support for multiple VxFS versions, the following
	patches are required.

	        PHCO_18462        diskusg_vxfs
	        PHCO_18463        fscat
	        PHCO_18464        getext
	        PHCO_18465        setext
	        PHCO_18466        vxdump
	        PHCO_18467        vxrestore
	        PHCO_18468        vxupgrade
	        PHCO_18470        df
	        PHCO_18471        fstyp
	        PHCO_18472        fs_wrapper
	        PHCO_18473        mount_wrapper
	        PHCO_19491        libc
	        PHCO_19623        mount_hfs
	        PHCO_19624        mount_cdfs
	        PHCO_19631        lvchange
	        PHCO_19656        mkboot
	        PHCO_19673        fsck_hfs

	Resolution:
	This is a recompile only.  The mount_hfs code calls a libc
	routine that changed to support VxFS version 4, so it
	needs to be recompiled with the newer libc.

	PHCO_16581:
	For "mount -F hfs -o quota", if quotactl() fails, an error
	code is passed back to generic mount(1M).  It should not
	return an error since a quotactl() failure only produces a
	warning.

	Resolution:
	When using "-o quota", if quotactl() fails in
	mount_hfs(1M), it now returns a 0, rather than an error
	code.  This is consistent with the behavior of
	mount_jfs(1M).  Looking at this patch stand-alone, the
	impact is simply that the return code is different.
	However, the impetus for this change was to cooperate with
	changes to the generic mount command involving /etc/mnttab
	access (see PHCO_16582).

	If the user has THIS mount_hfs patch and NOT the generic
	mount patch, there are no adverse effects.  They simply
	get
	the 0 return code when quotactl() fails, and the new entry
	is correctly added to /etc/mnttab.

	If the user has the generic mount patch and NOT THIS
	mount_hfs patch, then if quotactl() fails in mount_hfs, it
	returns an error code and, more importantly, the new entry
	will NOT get added to /etc/mnttab, even though the file
	system did get mounted; this is undesirable.  This is not
	likely to cause a critical situation for the user,
	especially since syncer will eventually come along (the
	default is every 30 seconds) and update /etc/mnttab
	correctly if it is out of sync with the kernel mount
	table.
	However, there will be a relatively small window where
	/etc/mnttab will not accurately reflect what is mounted;
	the newly mounted file system will not be there.  Again,
	note that this only affects when "-o quota" is used and
	the quotactl() fails.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHCO_19623

	5. Run swinstall to install the patch:

		swinstall -x autoreboot=true -x patch_match_target=true \
			  -s /tmp/PHCO_19623.depot

	By default swinstall will archive the original software in 
	/var/adm/sw/save/PHCO_19623.  If you do not wish to retain a
	copy of the original software, use the patch_save_files option:

		swinstall -x autoreboot=true -x patch_match_target=true \
			  -x patch_save_files=false -s /tmp/PHCO_19623.depot

	WARNING: If patch_save_files is false when a patch is installed,
		 the patch cannot be deinstalled.  Please be careful
		 when using this feature.

	For future reference, the contents of the PHCO_19623.text file is 
	available in the product readme:

		swlist -l product -a readme -d @ /tmp/PHCO_19623.depot
