 Description   

We can greatly reduce the build system complexity if we eliminate the recursive build of independent packages within the lustre tree. lustre-iokit is one of the recursive builds that should be eliminated.

Possible approaches are:

  1. Eliminate lustre-iokit.spec.in, and lustre-iokit's independent autotools system. Merge those parts into lustre's build system. lustre-iokit would be just another subpackage in lustre.spec.in.
  2. Move lustre-iokit out of the lustre tree and make it a stand-alone project.

Unlike with ldiskfs, I am going to recommend that we leave lustre-iokit in tree, but merge its build system into lustre.

The only reason I can see to move it out of tree is if people frequently need to build lustre-iokit on its own, independent of lustre.
