Fair enough.

When I was told that folks needed vmalloc under GFP_ATOMIC I didn't
question it any further:

https://lore.kernel.org/all/aeiHkG7X_dieMdw5@milan/

Looking back, it does look like it was never explained who these
folks are.

Ulazislau, so who needs vmalloc GFP_ATOMIC support in the kernel?
Or is it only used by out-of-kernel code?

Thanks,
