Description Shinobu KINJO 2017-04-10 01:46:40 UTC

Description of problem:
The customer has requested backporting the following upstream merged / unmerged patches:

 *1 https://review.openstack.org/#/c/374421/
 *2 https://bugs.launchpad.net/os-brick/+bug/1663925 (Unmerged)
 *3 https://review.openstack.org/#/c/433102/
 *4 https://bugs.launchpad.net/os-brick/+bug/1663936
 *5 https://review.openstack.org/#/c/433103/
 *6 https://bugs.launchpad.net/os-brick/+bug/1664032 (Unmerged)
 *7 https://review.openstack.org/#/c/433104/
 -8 https://github.com/open-iscsi/open-iscsi/pull/40
 -9 https://github.com/open-iscsi/open-iscsi/pull/49 (Unmerged)

* Since 8 and 9 are not related to os-brick but iscsi package in RHEL, we will create backport request for them separately.

Comment 4 Paul Grist 2017-04-12 03:22:03 UTC

Patches are posted for review, comprehensive testing is now passing on iSCSI (FC mpath will follow). 

The relevant patch set will actually be the following set and we will confirm the proper collection needed which may actually vary from the initial set proposed.  This BZ will be the right place to track status for the collection.
