OK so as I understand it that means that the line
hardware handler "1 emc 0 1"
now fails to function correctly because dm-emc no longer exists. That
makes this a functionality regression from 2.6.26 because of this

[SCSI] scsi_dh: Remove hardware handlers from dm
This patch removes the 3 hardware handlers that currently exist
under dm as the functionality is moved to SCSI layer in the earlier
patches.
Because we haven't actually moved all the functionality.
