Subject: Fwd: Question about how to fix numabalancing to work with isolated
 cpus?

Hi,
     I notice a problem that you guys discussed in the link below:

     https://lore.kernel.org/all/1491464210.4718.82.camel@gmx.de/T/
     "The isolated cpus are part of the cpus allowed list. In the above 
case,
      numabalancing ends up scheduling some of these tasks on isolated 
cpus. "

     I wonder if we're going to fix this eventually?

Thanks,
Guan Jing
