From 4513cb0c40d79599f72a5d1a6ab2fb279b63500d Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 14 Mar 2023 17:51:09 +0100 Subject: [PATCH] btrfs: move the bi_sector assignment out of btrfs_add_compressed_bio_pages Adding pages to a bio has nothing to do with the sector. Move the assignment to the two callers in preparation for cleaning up btrfs_add_compressed_bio_pages.
