Subject: scsi: include linux/scatterlist.h to pick up ARCH_HAS_SG_CHAIN
From: David Dillow <dillowda@xxxxxxxx>
If the compiled object doesn't include linux/scatterlist.h before
scsi/scsi.h, it will get an incorrect definition of
SCSI_MAX_SG_CHAIN_SEGMENTS.
This fixes an issue I found while working on the SRP initiator, where
linux/scatterlist.h was being pulled in by scsi/scsi_device.h. It's not
clear if I'm supposed to include linux/scatterlist.h myself, or if I'm
including the scsi headers in the wrong order. It makes sense for me that
scsi.h would pickup the needed headers itself to prevent confusion.
Another option is to potentially get rid of the ARCH_HAS_SG_CHAIN define
as all archs have it save m68knommu.
