[hwloc-devel] patch to execute command when using hwloc-bind --get

[John Donners]

Hi,

I was somewhat surprised to notice that hwloc-bind doesn't
execute the command if the --get option is used. This could
come in handy to check the binding set by other programs,
e.g. SLURM, mpirun or taskset. The following patch would
change this.

   }

   if (got_membind) {

Please consider this change for the next release of hwloc.

With regards,
John
