Current make_request based drivers use either blk_alloc_queue_node or
blk_alloc_queue to allocate a queue, and then set up the make_request_fn
function pointer and a few parameters using the blk_queue_make_request
helper.  Simplify this by passing the make_request pointer to
blk_alloc_queue, and while at it merge the _node variant into the main
helper by always passing a node_id, and remove the superfluous gfp_mask
parameter.  A lower-level __blk_alloc_queue is kept for the blk-mq case.

Why are you removing the non _node() variant? The memory allocation 
function for instance have this indirection as well and I don't think it 
simplifies a lot passing NUMA_NO_NODE in each block driver.

Because the two variants are rather pointless.  And this might get
more people to actually pass a useful node ID instead of copy and
pasting some old example code.

So then everybody will copy the NUMA_NO_NODE ones and in X years someone 
will come up with a wrapper passing in NUMA_NO_NODE to 
blk_alloc_queue_node(), because he/she didn't read the commit history.

But if I'm the only one objecting to it,

If you care about numa-node, then you are generally using it for other
allocations as well, so it should come naturally. If you don't, then
the copy/paste is fine. Better to expose it as the main API, so people
don't miss it.
