    Description

      Remove Lustre kernel patches to allow Lustre servers to be more easily ported to new kernels, and to be built against vendor kernels without changing the vendor kernel RPMs. There are a number of different patches, each one needs to use equivalent functionality which already exists in the kernel, or work to get the patch accepted upstream.
