I think we're nicely prepared for that conversion, we'll only need to add proper locking for the list of instance. The big problem with the pci_driver conversion is that lack of device ids in the driver. A few years ago I sent Achim a mail to ask if there's a definitive list of used PCI ids, but didn't get an answer - maybe the mail bounced. If we can't get this list we'd have to add something like 500 PCI ids from the ranges currently probed, which seems rather odd. gdth.h has various PCI_DEVICE_ID_ defines, maybe those are the supported ones? For eisa we'll probably have the same issue. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
