Never ever run NHC, even on an edge case that NHC_NO would still launch NHC
after.

Bug 3105.

Switch to list_for_each, and check if access list actually changed
after each update before updating last_prat_update. This prevents
the backfill scheduler from resetting mid-cycle unnecessarily.

Bug 3123.

Add "sbatch_wait_nodes" to SchedulerParameters to control default sbatch
    behaviour with respect to waiting for all allocated nodes to be ready for
    use. Job can override the configuration option using the --wait-all-nodes=#
    option.
bug 3120

Prior logic would treat execute line like this:
$ sbatch --wait-all-nodes -N3 tmp
with "-N3" as being the argument to the "--wait-all-nodes" option.
See bug 3120

Add salloc/sbatch/srun option --use-min-nodes to prefer smaller node counts
    when a range of node counts is specified (e.g. "-N 2-4").
bug 2996

Add salloc/sbatch/srun --priority option of "TOP" to set job priority to
    the highest possible value. This option is only available to Slurm operators
    and administrators.

Make sure no attempt is made to schedule a requeued job until all steps are
    cleaned (Node Health Check completes for all steps on a Cray).
bug 3082

Otherwise limit is checking the node count against the midplane count.

Bug 3049.

Check if node names are contiguous with respect to the node list
assigned to the partition, rather than just monotonically increasing.

capmc_suspend/resume - If a request modify NUMA or MCDRAM state on a set of
    nodes or reboot a set of nodes fails then just requeue the job and abort the
    entire operation rather than trying to operate on individual nodes.

Allow a node's PowerUp state flag to be cleared using update_node RPC.
bug 3100

When powering up a node to change it's state (e.g. KNL NUMA or MCDRAM mode)
    then pass to the ResumeProgram the job ID assigned to the nodes in the
    SLURM_JOB_ID environment variable.

Don't log error for job end_time being zero if node health check is still

Restore ability to manually power down nodes, broken in 15.08.12
in commit b4904661

The patch introduced in commit b4904661 (not powering down dead node) has a bad side effect.  Adding the "(node_ptr->last_idle != 0)" condition prevents from powering down nodes with the following command:

scontrol update nodename=nX state=power_down

because the state update function relies on zeroing the "last_idle" variable when a power_down is requested (see src/slurmctld/node_mgr.c, line 1589).

Reverting this commit should solve the problem...but I let you decide...

node_features/knl_cray: If a node is rebooted outside of Slurm's direction,

bug 3071

Fix race condition that could result in MCDRAM state information coming
  from capmc rather than cnselect (used state for next boot rather than
  latest boot).
bug 3080

No functional change, just silencing the warning message in this instance.

Modify srun task completion handling to only build the task/node string for

bug 3044

This reverts commit 1ec2a4ae.

Bug 3063.

Restructure srun command locking for task_exit processing logic for improved
  parallelism. This change decreases the amount of time consumed by serial
  logic by 2 orders of magnitude.
bug 3044

Preserve node "RESERVATION" state when one of multiple overlapping
    reservations ends. Previous logic would clear the node's
    RESERVATION state flag when any one of the reservations on the
    node ended rather than keeping the node in RESERVATION state
    until the last reservation ended.
bug 3057

Handle case when slurmctld daemon restart while compute node reboot in
    progress. Return node to service rather than setting DOWN.
bug 3042

Otherwise blade_cnt is potentially greater than

Bug 3033.

with hwloc.

This patch has two parts:
1. When a job is intially submitted, the Slurm was failing to set
   an initial reason for the job not starting.
2. After a job was submitted, it was sometimes failing to reset
   the job's reason. It was also failing to reset the "last_job_update"
   time, so something like "squeue -i1" would not get the new reason.
