From fe330305043f0b89132237fc0bbef66a040ebe90 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 4 Apr 2022 06:45:28 +0200 Subject: [PATCH] btrfs: stop using the btrfs_bio saved iter in index_rbio_pages The bios added to ->bio_list are the original bios fed into btrfs_map_bio, which are never advanced. Just use the iter in the bio itself.
