Commit c5f1ac8b authored by Bart Van Assche's avatar Bart Van Assche Committed by James Bottomley

Split SCSI header files

Move the constants that are used by both initiator and target
drivers into the new header file <scsi/scsi_proto.h>. This change
will allow to remove the initiator SCSI header include directives
from most SCSI target source files in a later patch.
