Doc Type:	Bug Fix
Doc Text:	Previously, the udev device manager automatically enabled all memory banks on IBM z System installations. As a consequence, hot plug memory was enabled automatically, which was incorrect. With this update, system architecture checks have been added to the udev rules to address the problem. As a result, hot plug memory is no longer automatically enabled.

Hello Red Hat / Lukas,
quick question ...
.
there are the following related bugs available:
.
RHBZ bug 1370161 - s390x standby memory automatically onlined after boot 
... fixed in RHEL7.3 RC ...
RHBZ bug 1375603 - s390x standby memory automatically onlined after boot [rhel-7.2.z] 
... which is the related 7.2.z zstream bug for RHBZ 1370161 ...
RHBZ bug 1381123 - s390x standby memory automatically onlined after boot [rhel-7.3.z]
... which is the related 7.3.z zstream bug for RHBZ 1370161 and which is 
this bugzilla ...
.
... now my question:
why is this 7.3.z zstream bugzilla 1381123 still needed
if the original issue is fixed already in RHEL7.3 RC through bug 1370161 ...?
Please advise ...
Thanks for your support.
