From 0f225f87873ee95dd4cf94dfc6a3249d4289e4ea Mon Sep 17 00:00:00 2001 From: John Garry Date: Thu, 22 Feb 2024 08:34:20 +0000 Subject: null_blk: Delete nullb.{queue_depth, nr_queues} Since commit 8b631f9cf0b8 ("null_blk: remove the bio based I/O path"), struct nullb members queue_depth and nr_queues are only ever written, so delete them. With that, null_exit_hctx() can also be deleted.
