From 49add4966d79244013fce35f95c6833fae82b8b1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 24 Jan 2022 10:11:06 +0100 Subject: block: pass a block_device and opf to bio_init Pass the block_device that we plan to use this bio for and the operation to bio_init to optimize the assignment. A NULL block_device can be passed, both for the passthrough case on a raw request_queue and to temporarily avoid refactoring some nasty code.
