Path Name: /hp-ux_patches/s700/10.X/PHKL_20355

Symptoms:
	PHKL_20355:
	(SR: 8606107556 CR: JAGab77814)
	Direct read may fail with error EFAULT.  ORACLE EBU is one
	of the applications affected.

	PHKL_19529:
	Installation of the AdvJFS product after the installation
	of PHKL_16750 results in an unpatched Adv JFS product. Fixes
	delivered by PHKL_16750 for AdvJFS are not present.

Defect Description:
	PHKL_20355:
	(SR: 8606107556 CR: JAGab77814)
	vx_dio_iovec() always returns EFAULT when vx_memiolock()
	fails.  Sometimes vx_memiolock() may be interrupted and in
	that case it returns EINTR.  This should be passed to the
	applications, instead of EFAULT so that they can retry the
	direct READ.

	Resolution:  Return the error, returned by vx_memiolock(),
	from vx_dio_iovec().

	PHKL_19529:
	( SR: 8606101067 CR: JAGab41307 )
	When PHKL_16750 is installed, and the AdvJFS project is not
	yet installed, all the files which would have been delivered
	for AdvJFS are not. The installed patch is therefore split.
	At a later time, when AdvJFS is installed in a well patched
	system, AdvJFS does not have the latest patched files and
	is exposed to already known and already fixed defects.
	Trying to reinstall PHKL_16750 at this point can be rather
	tedious since it involves removing all incremental patches
	depending on this base patch (PHKL_16750) before this last
	one can be removed. This is unacceptable.
