Prevent triggering gang scheduling within a partition if configured with
    PreemptType=partition_prio and PreemptMode=suspend,gang.
The essence of this fix is to change a "<=" to "<" in cons_res/job_test.c:
-               if ((p_ptr->part_ptr->priority <= jp_ptr->part_ptr->priority) &&
+               if ((p_ptr->part_ptr->priority < jp_ptr->part_ptr->priority) &&
but logic was also added to insure that a partition configuration with
PreemptMode did not override PreemptType != partition_prio.
bug 2232

Previously an error() would be logged when the attempt to open the job
script using the new directory format failed but the successive fallback to the
old directory structure was successful, leading to confusion when troubleshooting.

Move emitted warnings to debug(), and only error() after failing to open in both
directory structures. Add a note about backwards compatibility to both functions -
we cannot remove these fallbacks as directory structure for pending jobs does not
change on Slurm version update, and people may need to chain multiple version
update together to get to a current slurm version which would correctly update
slurmctld state files but leave pending jobs in the old directory structure.

Bug #2244.

If a job is requeued while in the process of being launch, remove it's
    job ID from slurmd's record of active jobs in order to avoid generating a
    duplicate job ID error when launched for the second time (which would
    drain the node).
bug 2240

In slurmctld log file, log duplicate job ID found by slurmd. Previously was
    being logged as prolog/epilog failure.

In both sched/basic and backfill: If a job can not be started due to some
    account/qos limit, then don't start other jobs which could delay jobs. The
    old logic would skip the job and start other jobs, which could delay the
    higher priority job.

Bug 2130

Full revert of c2fbf88f, 13b64c35 had caught part of this, but
this will revert it completely.  The code just wasn't needed in modern
Slurm.  It appears the patch came from an older version of Slurm that
didn't handle this correctly.

This reverts commit 29f25688.

Looks like this isn't needed, commit c2fbf88f doesn't appear to be needed
and is what is causing this issue.  c2fbf88f was added from an older
version of Slurm where this was already handled correctly in commit
