sil_dev_config - Apply device/host-specific errata fixups
void sil_dev_config(struct ata_device * dev);
Device to be examined
After the IDENTIFY [PACKET] DEVICE step is complete, and a device is known to be present, this function is called. We apply two errata
fixups which are specific to Silicon Image, a Seagate and a Maxtor fixup.
For certain Seagate devices, we must limit the maximum sectors to under 8K.
For certain Maxtor devices, we must not program the drive beyond udma5.
Both fixups are unfairly pessimistic. As soon as I get more information on these errata, I will create a more exhaustive list, and apply
the fixups to only the specific devices/hosts/firmwares that need it.
20040111 - Seagate drives affected by the Mod15Write bug are blacklisted The Maxtor quirk is in the blacklist, but I'm keeping the original
pessimistic fix for the following reasons... - There seems to be less info on it, only one device gleaned off the Windows driver, maybe
only one is affected. More info would be greatly appreciated. - But then again UDMA5 is hardly anything to complain about

device_rename - renames a device
int device_rename(struct device * dev, const char * new_name);
the pointer to the struct device to be renamed
the new name of the device
It is the responsibility of the caller to provide mutual exclusion between two different calls of device_rename on the same device to
ensure that new_name is valid and won't conflict with other devices.
Don't call this function. Currently, the networking layer calls this function, but that will change. The following text from Kay Sievers
Renaming devices is racy at many levels, symlinks and other stuff are not replaced atomically, and you get a "move" uevent, but it's not
easy to connect the event to the old and new device. Device nodes are not renamed at all, there isn't even support for that in the kernel
In the meantime, during renaming, your target name might be taken by another driver, creating conflicts. Or the old name is taken directly
after you renamed it -- then you get events for the same DEVPATH, before you even see the "move" event. It's just a mess, and nothing new
should ever rely on kernel device renaming. Besides that, it's not even implemented now for other things than (driver-core wise very
simple) network devices.
We are currently about to change network renaming in udev to completely disallow renaming of devices in the same namespace as the kernel
uses, because we can't solve the problems properly, that arise with swapping names of multiple interfaces without races. Means, renaming of
eth[0-9]* will only be allowed to some other name than eth[0-9]*, for the aforementioned reasons.
Make up a "real" name in the driver before you register anything, or add some other attributes for userspace to find the device, or use
udev to add symlinks -- but never rename kernel devices later, it's a complete mess. We don't even want to get into that and try to
implement the missing pieces in the core. We really have other pieces to fix in the driver core mess. :)
