Bug 3472

regcomp() is not safe to use across a fork in older glibc versions.
Reinitialize the keyvalue_re structure after the fork through an atfork()
handler.

Bug 3276.

This is a regression from commit b818dd9d

Basically the first AC_LINK_IFELSE sets whatever compiler we
are using to be that.  Since the above commit removed the BGL/P
code that was linked using C C++ became the compiler since the
next thing was BGQ in configure.ac to test against.

I just grabbed the DATABASES call, but any other one could had
worked.

another one.

This is the way it is done with the task plugins.  It appears this only
really matters when requesting 1 task with a full socket with exclusive
access.  This code would cyclically allocate sockets to the step instead
of filling up one socket then going to the next.

Fix for job constraint specification with counts, --ntasks-per-node value,
    and no node count.
bug 3470

Task/cray: Treat missing "mems" cgroup with "debug" messages rather than
    "error" messages. The file may be missing at step termination due to a
    change in how cgroups are released at job/step end.

Honor --ntasks-per-node and --ntasks option when used with job constraints
    that contain node counts.
bug 3458

Defer interactive job allocation until ALL allocated nodes are ready
  rather than after PrologSlurmctld (if any) completes.

Bug 3467.

burst_buffer/cray - Do not execute "pre_run" operation until after all nodes
    are booted and ready for use.

partitions.

Insure job does not start running before node is booted and PrologSlurmctld
    is complete.

Ported from 7a4aa7f2.

burst_buffer/cray - Support default pool which is not the first pool
    reported by DataWarp and log in Slurm when pools that are added or removed
    from DataWarp.

This reverts commit fd690a9c.

was there for jobs and steps, but for no real reason.  I couldn't see a
reason anyway.

Jobs preempted with PreemptMode=REQUEUE were incorrectly recorded as
REQUEUED in the accounting.

Fix srun I/O race condtion to eliminate a error message that might be
    generated if the application exits with outstanding stdin.
bug 3166

Properly set SLURM_JOB_GPUS environment variable for Prolog.
bug 3437

Clear job's reason of "BeginTime" in a more timely fashion and/or prevents
    them from being stuck in a PENDING state. There are multiple ways of
    clearing the reason, especially on a lightly loaded system, but the
    state can persist indefinitely on a heavily loaded system.
bug 3368

Fix to logic for getting expected start time of existing job ID with
    explicit begin time that is in the past. Previous logic would
    compare that (past) begin time with advanced reservations that
    would compete with it rather than the current time.

CRAY systems only: TaskPlugins must list task/cgroup before task/cray in
    order for the cgroup files to be created before task/cray runs. Without
    this change, the task/cray plugin frequently produces errors about the
    "mems" file being missing. The errors don't seem consistent, so this
    probably involves a race condition. Note that NERSC uses this order
    today and I changed read_config.c to produce a fatal error if the order
    is reversed.
