 Description   

This is caused by SERVER-45210. To fix this we will FCV gate that on 4.4, and if the fcv is 4.2 we will revert to the code used before SERVER-45210.

The bug in the BF is caused because nonAtomic causes the profiler namespace to change.

This ticket will only change the 4.4 branch.
