My take:  these changes lean more toward being a "clean up" rather
than fixing a problem that has significant impact.  The data in the sysfs
entries is bogus, but isn't actually hurting anything. The current code does
index off the end of an array in some cases, but the accesses are reads
and there's plenty of padding so that actually making an invalid memory
reference won't happen.   In the interest of reducing churn in the
stable branches, I would lean toward *not* backporting this to stable.
