Prevent background salloc disconnecting terminal at termination. Patch by Don Albert, Bull.

More than one TaskPlugin can be configured in a comma separated list.
Patch from Andriy Grytsenko (Massive Solutions Limited).

Fix error handling bug in mpi/mvapich plugin that could result in srun going into an infinite loop.

Avoid clearing a node's Arch, OS, BootTime and SlurmdStartTime when
    "scontrol reconfig" is run. Patch from Martin Perry, Bull.

Added scontrol ability to increment or decrement a job or step time limit.

would not be set correctly in the added child association.

With default configuration on non-Cray systems, enable salloc to be
spawned as a background process. Based upon work by Don Albert (Bull) and
Gerrit Renker (CSCS).

Add support to salloc for a new environment variable SALLOC_KILL_CMD,
which is equivalent to the -K/--kill-command option.

This fixes a bug which is thanks to a report by Don Albert.

The problem is that whenever salloc exits with a child process in stopped state
(suspended or stopped on terminal input/output), a zombie process is generated,
since this case is not caught by the code evaluating the child status.

This patch adds the missing case.  It uses SIGKILL, which is the only signal
that changes the state of a stopped process. It was decided not to try and
re-awken the process using SIGCONT, since (a) this happens during session
clean-up and (b) if the condition is due to SIGTTIN, the process immediately
becomes stopped again.
Patch from Gerrit Renker, CSCS.

Treat the specification of multiple cluster names as a fatal error.

Note that scontrol can only support a single cluster at one time.

Add -R/--reservation option to squeue command as a job filter.

Improve accuracy of REQUEST_JOB_WILL_RUN start time with respect to higher
priority pending jobs.

Expand explanation of multiple DEFAULT values in slurm.conf

Propagate DebugFlags changes by scontrol to the various plugins and
other modules. DebugFlags is cached in some places and the changes
cause the cache value to be reset as needed.

Disable use of SQUEUE_FORMAT env var if squeue -l, -o, or -s option is
used. Patch from Aaron Knister (UMBC).

association/wckey to be set incorrectly as a default the new object
was added after an original default object already existed.  Before
the slurmctld would need to be restarted to fix the issue.

If job's TMPDIR environment is not set or is not usable, reset to "/tmp".
Patch from Andriy Grytsenko (Massive Solutions Limited).

Regression from pre5.

Fix bug in GraceTime support for preempted jobs that prevented proper
operation when more than one job was being preempted. Based on patch from
Bill Brophy, Bull.

Add optional argument to srun's --kill-on-bad-exit so that user can set
its value to zero and override a SLURM configuration parameter of KillOnBadExit.

Add support for multiple sets of DEFAULT node, partition, and frontend
specifications in slurm.conf. New DEFAULT options overwrite old options,
but those not explicitly changed are preserved.

Patch from Andriy Grytsenko (Massive Solutions Limited).

Synchronize power-save module better with scheduler.
Without this change, returning a node to service was typically
delayed longer than necessary.
Patch from Andriy Grytsenko (Massive Solutions Limited).

Modify job expansion logic to support licenses, generic resources, and
currently running job steps in the job which is expanding.

BLUEGENE - if a block goes into an error state.  Fix issue where accounting wasn't updated correctly when the block was resumed.

When enforcing accounting, fix polling for unknown uids for users after the slurmctld started.  Previously one would have to issue a reconfigure to the slurmctld to have it look for new uids.
