    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.

            All of the kernels can run patchless now, and our testing has moved over to dm-flakey so the dev_readonly patches are no longer needed (and have been removed from 4.x kernels).

            I don't think that we can fully close out this ticket until servers only run on distros with kernels that include the project quotas patches. However, the option remains for those who prefer to use patchless servers rather than project quotas.
