Replace version borrowed from Linux 2.4.9 with newer version in 4.9.

burst_buffer/cray - Avoid "pre_run" operation if not using buffer (i.e.
    just creating or deleting a persistent burst buffer).
bug 3391

Previous job state information was "PENDING" rather than "REQUEUED"
  for each job requeued due to a burst buffer error.
bug 3388

scheduling a Datawarp job.

The assoc_mgr lock needs to happen before the bb_state.bb_mutex.  One place
this could cause deadlock is from src/slurmctld/controller.c
_accounting_cluster_ready() which calls clusteracct_storage_g_cluster_tres
which inturn calls bb_g_job_set_tres_cnt which calls bb_p_job_set_tres_cnt
which will lock the bb_muxtex after the assoc_mgr is already locked.

Bug 3331

Cache results of bit_set_count() calls.

Bug 3393.

The old logic would result in test16.4 failing some of the time.
  The failure was caused by the sattach command attaching to a
  job step before the original srun command received a
  RESPONSE_LAUNCH_TASKS message. That messsage  would then be sent
  to the salloc command. Since srun never got the message, it
  would hang. This change does not mark the job step as RUNNING
  until after the original srun gets sent the RESPONSE_LAUNCH_TASKS
  message and sattach requests are blocked until that time.

backfill scheduler: Stop trying to determine expected start time for a job
    after 2 seconds of wall time. This can happen if there are many running jobs
    and a pending job can not be started soon.

Bug 3364.

Configuring slurm with munge manually installed in /usr/local, with the
library in /usr/local/lib but an empty /usr/local/lib64 directory
will cause the munge plugins to look for libmunge.so in the wrong place.

The munge.spec file has historically provided libmunge.so as part of
munge-devel, which Slurm depends on already.

Add SchedulerParameters configuration parameter of "default_gbytes", which
    treats numeric only (no suffix) value for memory and tmp disk space as being
    in units of Gigabytes. Mostly for compatability with LSF.

Move BatchScript to end of each job's information when using
    "scontrol -dd show job" to make it more readable.

Can cause random assertion failures and core dumps due to differences
between definition in slurm.h and bitstring.h.

Inadverently introduced in 8967a4e7.

17.02 API has been changed so that node Port parameter is now packed and
unpacked on REQUEST_NODE_INFO RPC. Some client requests such as 'scontrol
write config', 'scontrol show node' will display the port if different
to SlurmdPort. Port parameter is also available now to 'sinfo' if
explicitly requested through '-O port' and to the 'sview' full node info.

Always send SlurmdPort in RPC even when in multiple-slurmd mode.

Bug 3376.

Fix security issue caused by insecure file path handling triggered by
the failure of a Prolog script. To exploit this a user needs to
anticipate or cause the Prolog to fail for their job.

(This commit is slightly different from the fix to the 15.08 branch.)

CVE-2016-10030.

Fix security issue caused by insecure file path handling triggered by
the failure of a Prolog script. To exploit this a user needs to
anticipate or cause the Prolog to fail for their job.

CVE-2016-10030.

Prevent "stray" jobs from using resources when the srun/salloc
will never launch the actual compute tasks.

Bug 3344.

PluginDir is allowed to be a PATH-style list of directories; remove
incorrect test of the variable as if it were a single directory and
comment that the check for that is elsewhere.

Bug 3361.

Add SchedulerParameters option of spec_cores_first to select specialized
    cores from the lowest rather than highest number cores and sockets.
bug 3349

Null terminate before strchr().

This is a new message when "PrologFlags=contain" or
  "PrologFlags=alloc" is configured.
bug 3351

Cancel interactive job if Prolog failure with "PrologFlags=contain"
    configured.
bug 3351

Do not allocate specialized cores to jobs using the --exclusive option.
bug 3349

Fix memory and file descriptor leaks in slurmd daemon's sbcast logic.

The part_ptr is sent into the function, there is no reason to look it up
again.  Coverity reported this.

Remove req_node_layout, which was only used with wiki/wiki2.
This leads to removal of _get_cpu_cnt() as well.

Remove SchedulerPort, only used for communication to Moab/Maui.
Remove slurm_get_sched_port() from API.
Remove schedport from slurm_ctl_conf struct.

version is lower than the min version, set it to the min.

sched/backfill - Fix logic to reserve resources for jobs that require a

Fix for possible infinite loop in select/cons_res plugin when trying to
