commit 0bd97a8061c2ebbe792da8b662c5d19b2f1af02c
Author: William Cohen <wcohen@redhat.com>
Date: Mon Sep 13 21:32:38 2021 -0400
Use task_state tapset function to avoid task_struct changes
The Linux 5.14 kernel's task_struct changed the state field to
__state. The task_state tapset function selects the appropriate
version. Make the scheduler.stp tapset and schedtimes.stp example use
the task_state function rather than directly trying to access the
task_struct state field (and get it wrong for newer kernels).
