If the other sending side has write_tsc_info from 4.6+, then _res1 is zero. If it is older, the XC_SAVE_ID_TSC_INFO is eventually not handled anymore. At least I could not find the relevant code, even in staging-4.6. But then, it is unlikely that migration from 4.5 to 4.6 did not work. Also, in general the input comes from "remote". So it is untrusted. Olaf
