From 200052440d3b56f593038a35b7c14bdc780184a9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Matias=20Bj=C3=B8rling?= Date: Sat, 21 Dec 2013 00:11:00 +0100 Subject: null_blk: set use_per_node_hctx param to false The defaults for the module is to instantiate itself with blk-mq and a submit queue for each CPU node in the system. To save resources, initialize instead with a single submit queue.
