This might have worked fine for core reservations or when there
are sufficient idle nodes to use, the the select_g_resv_test()
function clears the node bitmap for nodes that it can not use
and the reservation create logic did not restore that bitmap
after a failed resource selection attempt. This logic restores
the node bitmap on a failed call to select_g_resv_test() so we
can add nodes to the bitmap of available nodes rather than having
it repeatedly cleared.
The logic also adds some performance enhancements that I will
add to in the next commit.

on a task level if any task hit it the check will be triggered)

use mem and memsw failcnt, check for existence

Thanks Ryan.  I'll let you know how it goes.

task/cgroup: notify if memory.memsw.failcnt > 0. indicates oom

Thanks Ryan, this looks correct.

Correction to hostlist parsing bug introduced in v2.6.4 for hostlists with
more than one numeric range in brackets (e.g. rack[0-3]_blade[0-63]").
bug505

Avoid decrementing grp_used_cpu_run_secs if we are not enforcing
accounting limits. Without this change, the plugin will decrement
times from zero cpu used times (i.e decrement an uninitialized
variable).

Add argument to priority plugin's priority_p_reconfig function to note
when the association and QOS used_cpu_run_secs field has been reset.
Without this flag, we remove time on "scontrol setdebug" or
"scontrol setdebugflag" that can result in used_cpu_run_secs
going negative or otherwise get bad values.

Add support for dependencies of job array elements (e.g.
"sbatch --depend=afterok:123_4 ..."). This does not support
depenendencies of ALL job array elements, only individual job
array elements.

preforms the allocation, regression in 2.6.3.
