From 07888c665b405b1cd3577ddebfeb74f4717a84c4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 24 Jan 2022 10:11:05 +0100 Subject: block: pass a block_device and opf to bio_alloc Pass the block_device and operation that we plan to use this bio for to bio_alloc to optimize the assignment. NULL/0 can be passed, both for the passthrough case on a raw request_queue and to temporarily avoid refactoring some nasty code. Also move the gfp_mask argument after the nr_vecs argument for a much more logical calling convention matching what most of the kernel does.
