Forgot to mention the valgrind version:

==24339== Memcheck, a memory error detector
==24339== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et al.
==24339== Using Valgrind-3.16.0 and LibVEX; rerun with -h for copyright info
Comment 2 Mark Wielaard 2020-06-03 13:29:25 UTC 
315 is sched_getattr on amd64
https://www.man7.org/linux/man-pages/man2/sched_getattr.2.html
which indeed hasn't been supported
Comment 3 Mark Wielaard 2020-06-03 13:32:36 UTC 
Seems this was already reported 4 (!) years ago and someone did propose a patch. Time to get this fixed.
