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

Add salloc_wait_nodes option to the SchedulerParameters parameter in the
    slurm.conf file controlling when the salloc command returns in relation to
    when nodes are ready for use (i.e. booted).

sched/backfill - Check that a user's QOS is allowed to use a partition
    before trying to schedule resources on that partition for the job.

Otherwise blade_cnt is potentially greater than
bit_size(jobinfo->blade_map) which leads to an assertion failure.

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.
bug 3025

Fix multipart srun submission with EnforcePartLimits=NO and job violating
    the partition limits.

If all GRES were not defined on all nodes OR if a regular expression was used
   for a GRES file configuration (e.g. in gres.conf
   "Type=gpu Files=/dev/nvidia[0-4]"), then memory corruption was likely.
   The logic has been bad since its inception several years ago.

POLLRDHUP does not exist on BSD, define to POLLHUP as done elsewhere.

The attached patch switches to a more reliable method of detecting
service nodes, using xtcli status. In addition, it switches to the print
function to be better compatible with python 3.

To ease the distribution process, plugin names will be automatically
adjusted to identify the version of API that it can support,
ie: pmix_v1 and pmix_v2.
This provides the ability for distro's to create separate
non-conflicting packages for each API generation.

Bug 2986

Insure reported expected job start time is not in the past for pending jobs.
bug 3002

burst_buffer/cray: Requeue, but do not hold a job which fails the pre_run
    operation.
bug 3009

Only mark job_id as zero for batch step (when all job steps would be
cleared), not for individual steps which prevented successive steps
from being cancelled.

Bug 2984.

slurmstepd modified to pre-load all relevant plugins at startup to avoid
    the possibility of modified plugins later resulting in inconsistent API
    or data structures and a failure of slurmstepd.

Bug 2983.

Don't about step launch if job reaches expected end time while node is
    configuring/booting (NOTE: The job end time will be adjusted after node
    becomes ready for use).

Filesystem instead of Lustre.

Network dataset.

Locking slurmstepd in memory can result in exhausting real memory
  in some cases, resulting in failure of the slurmstepd process.
  This reverts commit 03cf4a5d,
  but the logic will be returned using a configuration parameter
  in Slurm version 17.02.

This should improve performance and prevent failure if a local
  group ID lookup fails.
bug 2928

Prevent slurmd abort if hwloc library fails to populate the "children"
    arrays (observed with hwloc version "dev-333-g85ea6e4").

Make EnforcePartLimit support logic work with any ordering of partitions
    in job submit request.

Calculation switched the node count in place of the cpu count, which
results in incorrect estimates.
