Subject: [PATCH 0/1] block: fix blk_queue_split() resource exhaustion

Result of RFC previously discussed here:
https://lkml.org/lkml/2016/6/22/172
[RFC] block: fix blk_queue_split() resource exhaustion

Rebased to linux-block/for-4.8/core as of today.
Would also need to go to Stable 4.3 and later.
