I just got:

  Building modules, stage 2.
  MODPOST 414 modules
ERROR: "scsi_normalize_sense" [drivers/md/dm-rdac.ko] undefined!
make[1]: *** [__modpost] Error 1

Presumably DM_MULTIPATH_RDAC needs to depend on SCSI (not enabled
here) since it uses scsi_normalize_sense.

It does, but "rdac" _is_ for a SCSI device.

What device are you using it with ?

It does __what__ ?  depend on SCSI?
I don't see that in drivers/md/Kconfig.
Sounds like Martin is correct, SCSI needs to be added, like below.

DM_MULTIPATH_RDAC uses SCSI API(s) and is for a SCSI device,
so add SCSI to its depends on to prevent build errors.

Not tested.

Yes, as you understood it correctly :)

I do agree that the following patch would be needed.

Since the rdac hardware handler is for a scsi device, including it
without SCSI would not achieve anything (as his device won't be visible
in the first place). Hence my question.

For completeness, I agree that we need the fix pointed below.

I'm not using it at all.  I merely compiled a kernel where
DM_MULTIPATH_RDAC was activated by chance without SCSI.  Randy's patch
looks good.

Tested-by: Martin Michlmayr <tbm@cyrius.com>

This works for me.  Please make sure it'll go into 2.6.23.
