v2.2 slurmd will work with an earlier slurmstepd.

release of slurm

    for jobs and job steps as a percentage of their real memory allocation.

    S_STEP_ALLOC_MEM. Support will remain for S_JOB_ALLOC_CORES and
    S_JOB_ALLOC_MEM.
Kill individual job steps that exceed their memory limit rather than
    killing an entire job if one step exceeds its memory limit.

Much functionality has been added to account_storage/pgsql.  The plugin is still in a very beta state.  It is still highly advised to use the mysql plugin, but if you feel like living on the edge or just really like postgres over mysql for some reason here you go. (Work done primarily by Hongjia Cao, NUDT.)

with slurm_get_state_save_location() to eliminate need
for locking.

modify test4.11 to match

 clean up some related code for reservations and partitions.

  NOTE: There will be no change in behavior unless partition configuration 
  or node Features/Weight are altered using the scontrol command to differ 
  from the contents of the slurm.conf configuration file.

  Preserve current partition state information plus node Feature and Weight 
  state information after slurmctld receives a SIGHUP signal or is restarted 
  with the -R option. Recreate partition plus node information (except node
  State and Reason) from slurm.conf file after executing "scontrol reconfig" 
  or restarting slurmctld *without* the -R option. 

     OPERATION            ACTION
     slurmctld -R         Recover all job, node and partition state
     slurmctld            Recover job state, recreate node and partition state
     slurmctld -c         Recover no jobs, recreate node and partition state
     SIGHUP to slurmctld  Preserve all job, node and partition state
     scontrol reconfig    Preserve job state, recreate node and partition state

  Old logic preserved node Feature plus partition state after "slurmctld" or 
  "scontrol reconfig" rather than recreating it from slurm.conf. Node Weight 
  was formerly always recreated from slurm.conf. 

    logging of "access granted for user ...", access denied and other errors
    will still be logged.

    of slurm.conf file after slurmctld restart or reconfiguration.

Moved all SQL dependant plugins into a seperate rpm slurm-sql.  This should be needed only where a connection to a database is needed (i.e. where the slurmdbd is running)
