What I have in mind is actually this: We implement commands to trigger the scsi_complete_async_scans() using *both* the (legacy, agreed) /proc/scsi/scsi interface _and_ using a sysfs attribute for this (either in /sys/module/scsi_mod/parameter/, using a module_param_call as Roland suggested, or, create a new /sys/module/scsi_mod/<whatever>/wait_..., whatever is appropriate).
/proc/scsi/scsi is now deprecated _because_ the sysfs alternative became available, after all (we couldn't pull functionality / interfaces previously exposed to userspace from under them without giving equivalent alternatives anyway).
However, Ben does have a point that we shouldn't force those using SCSI (and wishing to use the new async scanning feature) to depend on and use sysfs too, so those like him could use /proc/scsi/scsi. The idea is that with time sysfs gets its act together and thus becomes standard enough on all Linux boxen (much like /proc is today), and those like Ben could later switch to that. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
