From 380fd06640a7afe972e45310012c3e22d9c4783d Mon Sep 17 00:00:00 2001 From: Misono Tomohiro Date: Thu, 30 Aug 2018 10:59:16 +0900 Subject: [PATCH] btrfs: remove redundant variable from btrfs_cross_ref_exist Since commit d7df2c796d7e ("Btrfs attach delayed ref updates to delayed ref heads"), check_delayed_ref() won't return -ENOENT. In btrfs_cross_ref_exist(), two variables 'ret' and 'ret2' are originally used to handle -ENOENT error case. Since the code is not needed anymore, let's just remove 'ret2'.
