From e19182c0fff451e3744c1107d98f072e7ca377a0 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Mon, 4 Dec 2017 13:11:45 -0500 Subject: btrfs: fix missing error return in btrfs_drop_snapshot If btrfs_del_root fails in btrfs_drop_snapshot, we'll pick up the error but then return 0 anyway due to mixing err and ret.
