The code in block/scsi_ioctl.c exists in the block layer since until
recently most of it was used by both the IDE and SCSI code. Now that
drivers/ide is gone (thanks Christoph!), how about moving block/bsg.c
and block/scsi_ioctl.c to drivers/scsi/? As far as I can see the BSG
code is only used by SCSI drivers:

$ git grep -nH BLK_DEV_BSG | grep /Kconfig
block/Kconfig:38:config BLK_DEV_BSG
block/Kconfig:57:config BLK_DEV_BSGLIB
block/Kconfig:59:       select BLK_DEV_BSG
drivers/scsi/Kconfig:231:       select BLK_DEV_BSGLIB
drivers/scsi/Kconfig:241:       select BLK_DEV_BSGLIB
drivers/scsi/Kconfig:250:       select BLK_DEV_BSGLIB
drivers/scsi/libsas/Kconfig:13: select BLK_DEV_BSGLIB
drivers/scsi/ufs/Kconfig:150:   select BLK_DEV_BSGLIB

The block/scsi_ioctl.c code is used more widely however:

$ git grep -nH BLK_SCSI_REQUEST | grep /Kconfig
block/Kconfig:32:config BLK_SCSI_REQUEST
block/Kconfig:41:       select BLK_SCSI_REQUEST
block/Kconfig:60:       select BLK_SCSI_REQUEST
drivers/block/Kconfig:77:       select BLK_SCSI_REQUEST
drivers/block/Kconfig:309:      select BLK_SCSI_REQUEST
drivers/block/paride/Kconfig:30:        select BLK_SCSI_REQUEST
drivers/scsi/Kconfig:22:        select BLK_SCSI_REQUEST
drivers/target/Kconfig:8:       select BLK_SCSI_REQUEST
fs/nfsd/Kconfig:112:    select BLK_SCSI_REQUEST
