git-scsi-misc adds this:
struct scsi_eh_save {
int result;
enum dma_data_direction data_direction;
unsigned char cmd_len;
unsigned char cmnd[MAX_COMMAND_SIZE];
void *buffer;
unsigned bufflen;
unsigned short use_sg;
int resid;
struct scatterlist sense_sgl;
};
which will not compile unless the includer has earlier included
scatterlist.h.
