The following two header files have the same file name: include/scsi/scsi.h and drivers/scsi/scsi.h. This is confusing. Remove the latter since the following note was added in drivers/scsi/scsi.h in 2004: "NOTE: this file only contains compatibility glue for old drivers. All these wrappers will be removed sooner or later. For new code please use the interfaces declared in the headers in include/scsi/" Link: https://lore.kernel.org/r/20220218195117.25689-7-bvanassche@acm.org Cc: Christoph Hellwig <hch@lst.de> Cc: Ming Lei <ming.lei@redhat.com> Reviewed-by: Hannes Reinecke <hare@suse.com> Reviewed-by: Himanshu Madhani <himanshu.madhani@oracle.com> Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Martin K.
