Masami Hiramatsu (Google) cb6fcef8b4 objpool: fix to make percpu slot allocation more robust
Since gfp & GFP_ATOMIC == GFP_ATOMIC is true for GFP_KERNEL | GFP_HIGH, it
will use kmalloc if user specifies that combination.  Here the reason why
combining the __vmalloc_node() and kmalloc_node() is that the vmalloc does
not support all GFP flag, especially GFP_ATOMIC.  So we should check if
gfp & (GFP_ATOMIC | GFP_KERNEL) != GFP_ATOMIC for vmalloc first.  This
ensures caller can sleep.  And for the robustness, even if vmalloc fails,
it should retry with kmalloc to allocate it.
