Well, the hint amounted to "don't do vmalloc if you cannot live with the
GFP_KERNEL" allocations.
Which email is that?
I only see where David says to implement vmalloc_node_gfp() and the talk
was about if that makes sense from a style perspective and then dies.
Anyway, this only seems to affect ptlrpc_alloc_rqbd() since I think
that's the only place which calls OBD_CPT_ALLOC_PTR(). The rest can use
__vmalloc().
