[PATCH] ide: ide-generic, allow for capture of other unsupported devices
The ide-generic driver gives you DMA at bios tuned speed so can actually run a
lot of unsupported devices quite well. It has a pci table so that it doesn't
grab disks owned by other drivers but no way to override this. The patch adds
an option ide-generic-all which makes the driver grab everything going that is
IDE class.
The diff is messy because I put the special case as case 0 to make the if
conditional and long term maintenance easier.
This has been in Fedora for some time.
