Description Florian Weimer 2021-12-09 23:02:38 UTC 
+++ This bug was initially created as a clone of Bug #2030870 +++

We plan to backport rseq-backed sched_getcpu into Red Hat Enterprise Linux 9 (bug 2024347).

--2062070-- WARNING: unhandled amd64-linux syscall: 334
--2062070-- You may be able to write your own handler.
--2062070-- Read the file README_MISSING_SYSCALL_OR_IOCTL.
--2062070-- Nevertheless we consider this a bug.  Please report
--2062070-- it at http://valgrind.org/support/bug_reports.html.

Failing the rseq system call with ENOSYS is fine, there is a fallback.
