Out of curiosity and for my own edification:  What *is* GFP_ATOMIC meant 

for?

It is meant as you used it, _except_ for !PREEMPT_RT.

With PREEMPT_RT all allocators are fully preemptable, that is both the
slab as well as the underlying page allocator.

Allocation from atomic context is a BUG() with -rt.

Thanks for the clarification!
