From: Filipe Manana Date: Mon, 15 Jun 2020 09:36:48 +0000 (+0100) Subject: btrfs: remove no longer used log_list member of struct btrfs_ordered_extent X-Git-Tag: v5.10.7~1563^2~156 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cd8d39f4aeb3b69af2478112366584256248eb2b;p=platform%2Fkernel%2Flinux-rpi.git btrfs: remove no longer used log_list member of struct btrfs_ordered_extent The 'log_list' member of an ordered extent was used keep track of which ordered extents we needed to wait after logging metadata, but is not used anymore since commit 5636cf7d6dc86f ("btrfs: remove the logged extents infrastructure"), as we now always wait on ordered extent completion before logging metadata. So just remove it since it's doing nothing and making each ordered extent structure waste more memory (2 pointers).
