Perhaps a start of this would be something like the below for a new
MAINTAINERS entry just for SCSI CORE.

This adds an "E:" patch prefix entry as well as a specific file
list for what seem to be "scsi core" files so that the generic
SCSI SUBSYSTEM F:drivers/scsi/ entry does not have to be used.

The SCSI SUBSYSTEM could have an E: entry of "scsi:" so that
driver specific content could be automatically prefixed with
"scsi: <basename(dirname)>:
