Subject: scsi_get_lba breakage in 5.10 -- Re: Linux 5.10.206

This is bad idea. This changes return value, but without fixing
callers; there will be subtle bugs somewhere.
At minimum, we need this:
87662a472a9d8980b26ba5803447df2c4981d467 scsi: iser: Use scsi_get_sector() instead of scsi_get_lba()
That will fix iser, but there's also:
drivers/s390/scsi/zfcp_fsf.c: io->ref_tag_value = scsi_get_lba(scsi_cmnd) & 0xFFFFFFFF;
drivers/scsi/isci/request.c: tc->ref_tag_seed_gen = scsi_get_lba(scmd) & 0xffffffff;
drivers/scsi/isci/request.c: tc->ref_tag_seed_verify = scsi_get_lba(scmd) & 0xffffffff;
drivers/scsi/lpfc/lpfc_scsi.c: lba = scsi_get_lba(sc);
drivers/scsi/lpfc/lpfc_scsi.c: reftag = (uint32_t)scsi_get_lba(sc); /* Truncate LBA */
drivers/scsi/lpfc/lpfc_scsi.c: reftag = (uint32_t)scsi_get_lba(sc); /* Truncate LBA */
drivers/scsi/lpfc/lpfc_scsi.c: reftag = (uint32_t)scsi_get_lba(sc); /* Truncate LBA */
drivers/scsi/lpfc/lpfc_scsi.c: reftag = (uint32_t)scsi_get_lba(sc); /* Truncate LBA */
drivers/scsi/lpfc/lpfc_scsi.c: start_ref_tag = (uint32_t)scsi_get_lba(cmd); /* Truncate LBA */
drivers/scsi/lpfc/lpfc_scsi.c: (unsigned long)scsi_get_lba(cmd),
drivers/scsi/lpfc/lpfc_scsi.c: (unsigned long)scsi_get_lba(cmd),
drivers/scsi/lpfc/lpfc_scsi.c: (unsigned long)scsi_get_lba(cmd),
drivers/scsi/lpfc/lpfc_scsi.c: (unsigned long long)scsi_get_lba(cmd),
drivers/scsi/lpfc/lpfc_scsi.c: (unsigned long long)scsi_get_lba(cmd),
drivers/scsi/lpfc/lpfc_scsi.c: (unsigned long long)scsi_get_lba(cmd),
drivers/scsi/lpfc/lpfc_scsi.c: (unsigned long long)scsi_get_lba(cmd),
drivers/scsi/lpfc/lpfc_scsi.c: (unsigned long long)scsi_get_lba(cmd),
drivers/scsi/lpfc/lpfc_scsi.c: failing_sector = scsi_get_lba(cmd);
drivers/scsi/lpfc/lpfc_scsi.c: (unsigned long long)scsi_get_lba(cmd),
drivers/scsi/lpfc/lpfc_scsi.c: (unsigned long long)scsi_get_lba(cmnd),
drivers/scsi/lpfc/lpfc_scsi.c: (unsigned long long)scsi_get_lba(cmnd),
drivers/scsi/qla2xxx/qla_iocb.c: (0xffffffff & scsi_get_lba(cmd)));
drivers/scsi/qla2xxx/qla_iocb.c: (0xffffffff & scsi_get_lba(cmd)));
drivers/scsi/qla2xxx/qla_iocb.c: (0xffffffff & scsi_get_lba(cmd)));
drivers/scsi/qla2xxx/qla_isr.c: cmd->cmnd[0], (u64)scsi_get_lba(cmd), a_ref_tag, e_ref_tag,
drivers/scsi/qla2xxx/qla_isr.c: sector_t lba_s = scsi_get_lba(cmd);
include/scsi/scsi_cmnd.h:static inline sector_t scsi_get_lba(struct scsi_cmnd *scmd)
That needs to be fixed somehow. This may be quite critical due to data
corruption...?
Best regards,
Pavel
