The number of prerequisite fixes before we can apply the fix 748935eeb72c343 makes this a rather overly involved fix. I doubt it will be SRU'able. Since this *only* occurs when accessing two TPM related interfaces in a fast multiple multi-threaded race on a few specific x86 devices as root makes this a very risky set of backport changes for such a corner case.
For now, I'm going to force stress-ng sysfs test to skip the tpm files for older kernels to workaround this issue. (Ugh).
