From 74fa8f9c553f7b5ccab7d103acae63cc2e080465 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 15 Feb 2024 08:10:47 +0100 Subject: block: pass a queue_limits argument to blk_alloc_disk Pass a queue_limits to blk_alloc_disk and apply it if non-NULL. This will allow allocating queues with valid queue limits instead of setting the values one at a time later. Also change blk_alloc_disk to return an ERR_PTR instead of just NULL which can't distinguish errors.
