Recently it has been proposed to discuss how to add scsi-mq support in
the iSER initiator during the 2015 edition of the LSF/MM summit. In the
discussion that followed that proposal several questions were asked
about how scsi-mq support has been added in the SRP initiator driver,
which design choices have been made and which lessons have been learned.
Hence the proposal to add a topic to the LSF/MM schedule for reporting
how scsi-mq support has been added in the SRP initiator.
For the actual discussion see also Sagi Grimberg, [LSF/MM TOPIC] iSCSI
MQ adoption via MCS discussion, linux-scsi mailing list, January 7, 2015
(http://thread.gmane.org/gmane.linux.scsi/98199).
Christoph and Mike, if you would like to complement this topic with a
presentation about the scsi-mq core itself and/or integration of
multiqueue support in the device mapper multipath driver, I would
welcome this.
Bart.

A big long blk-mq / scsi-mq sessions sounds like a good plan. That
can include a brief overview of the existing work and all the
still pending bits for iSCSI/iSER, multipath and so on.
