Hi!

I test recent kernels in this set-up, so I included the output of
"uname" in case that is relevant.

[kdevops@ltp-notify ~]$ uname -r
6.15.0-rc6-g7278569740f6
[kdevops@ltp-notify ~]$ rpm -qf /usr/include/linux/sched/types.h
kernel-headers-5.14.0-570.17.1.el9_6.x86_64
[kdevops@ltp-notify ~]$ rpm -qf /usr/include/bits/sched.h
glibc-headers-2.34-168.el9_6.14.x86_64
[kdevops@ltp-notify ~]$ cat /etc/redhat-release
Red Hat Enterprise Linux release 9.6 (Plow)
[kdevops@ltp-notify ~]$

I guess one thing I might try is running the ltp build on a stock
RHEL 9.6 kernel. I'm not sure if the test workflow replaces the
kernel headers under /usr/include.
