From edb0872f44ec9976ea6d052cb4b93cd2d23ac2ba Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 9 Aug 2021 16:17:43 +0200 Subject: block: move the bdi from the request_queue to the gendisk The backing device information only makes sense for file system I/O, and thus belongs into the gendisk and not the lower level request_queue structure. Move it there.
