this is to announce that we'll soon drop CONFIG_IDE support from all kernels. CONFIG_IDE is already disabled for all architectures except ppc64le and ppc64 on TW, and ppc64le on Leap. SLE hasn't had legacy IDE support since SLE12.
Note that this is only about "legacy IDE" support. libata-based devices will of course remain supported. We doubt that any real, currently supported hardware requires the legacy IDE drivers. So if you're using /dev/hdX devices on TW or Leap, ppc64 or ppc64le, please speak up.
