Predator and CL could not provide any possible suspects.

Using Code Search for the file, "partition_alloc.h" suspecting the below Cl might have caused this issue

palmer@ -- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks!
