This structure is accessed by the device; the fewer Linux things in it, the better. Using the pci_dev pointer from the hostdata requires a lot of changes: - Pass Scsi_Host to a lot of routines which currently take a sym_hcb. - Set the Scsi_Host as the pci drvdata (instead of the sym_hcb) Signed-off-by: Matthew Wilcox <willy@xxxxxxxxxxxxxxx>
Obviously this is a judgement call on your part... but did you at least consider passing sym_hcb for all cases instead?
This is a common driver decisions, and many authors choose to store a pointer to the kernel struct (Scsi_Host in this case) in their adapter private structure, since it is often _far_ more common to pass the driver-private struct in arguments.
It doesn't make much sense to do the additional indirection IFF the majority of the routine actually want the driver-private structure.
I ACK the patch either way... - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
