    Description

      In tracking down the root cause of LU-5043, I went through the cpu partitioning code in Lustre and found some of it rather difficult to follow. A number of not-necessarily-safe assumptions seem to made, with no code comments explaining what was assumed and why. I think we have some technical debt to deal with here.
