Can we use current_path[] as last element and flex array (same as what
we have today under struct nvme_ns_head) so that we don't need to
allocate array as big as MAX_NUMANODES? With flex array we can use
num_possible_nodes() which may be much smaller than MAX_NUMANODES.
Sure, I don't see a problem with that. I think that using MAX_NUMNODES
was a leftover from an earlier dev approach.
Thanks!
