Title:
  WARNING: unhandled amd64-linux syscall: 315

Status in valgrind package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  Valgrind shipped with focal does not support the sched_getattr and
  sched_setattr syscalls, resulting in output like

  --1234-- WARNING: unhandled amd64-linux syscall: 315
  --1234-- You may be able to write your own handler.
  --1234-- Read the file README_MISSING_SYSCALL_OR_IOCTL.
  --1234-- Nevertheless we consider this a bug.  Please report
  --1234-- it at http://valgrind.org/support/bug_reports.html.

  This has been fixed upstream in the meanwhile.

  Could it be possible to cherry pick
  6323fd5bfd94c3f80e2ff44f16488e0172bd9a96 into valgrind shipped with
  focal? Lots of applications make use of those syscalls.
