- * This file was inttroduced to resolve XT3 (Catamount) build issues.
- * The orignal idea was to move <lustre/types.h> here however at
- * the time of this writing
- * it's unclear what external dependencies are tied
- * to that file (It's not just some source file #including it)
- * there is some build/packaging infrastructure that includes it.
- * Hopefully that will be resolved shortly, that file will
- * be removed, its contents copied here and this comment can be deleted.
