Improve readability of the code in the SCSI core by introducing an enumeration type for the values used internally that decide how to continue processing a SCSI command. The eh_*_handler return values have not been changed because that would involve modifying all SCSI drivers. The output of the following command has been inspected to verify that no out-of-range values are assigned to a variable of type enum scsi_disposition: KCFLAGS=-Wassign-enum make CC=clang W=1 drivers/scsi/ Link: https://lore.kernel.org/r/20210415220826.29438-6-bvanassche@acm.org Cc: Christoph Hellwig <hch@lst.de> Cc: Johannes Thumshirn <johannes.thumshirn@wdc.com> Cc: Hannes Reinecke <hare@suse.de> Cc: Daniel Wagner <dwagner@suse.de> Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Martin K.
