From c90322fc9badf8facf70d4256f254f8e5e6b87bf Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 23 May 2022 14:43:02 +0200 Subject: [PATCH] block: use bio_queue_enter instead of blk_queue_enter in bio_poll [ Upstream commit ebd076bf7d5deef488ec7ebc3fdbf781eafae269 ] We want to have a valid live gendisk to call ->poll and not just a request_queue, so call the right helper.
