#     
#     Pull scheduler fixes from Thomas Gleixner:
#      "A set of scheduler updates:
#     
#        - Prevent PSI state corruption when schedule() races with cgroup
#          move.
#     
#          A recent commit combined two PSI callbacks to reduce the number of
#          cgroup tree updates, but missed that schedule() can drop rq::lock
#          for load balancing, which opens the race window for
#          cgroup_move_task() which then observes half updated state.
#     
#          The fix is to solely use task::ps_flags instead of looking at the
#          potentially mismatching scheduler state
#     
#        - Prevent an out-of-bounds access in uclamp caused bu a rounding
#          division which can lead to an off-by-one error exceeding the
#          buckets array size.
#     
#        - Prevent unfairness caused by missing load decay when a task is
#          attached to a cfs runqueue.
#     
#          The old load of the task was attached to the runqueue and never
#          removed. Fix it by enforcing the load update through the hierarchy
#          for unthrottled run queue instances.
#     
#        - A documentation fix fot the 'sched_verbose' command line option"
