From 4198479524aeccaf53c3a4cc73784982535573fa Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Mon, 21 Jan 2019 11:48:06 +0100 Subject: binderfs: kill_litter_super() before cleanup Al pointed out that first calling kill_litter_super() before cleaning up info is more correct since destroying info doesn't depend on the state of the dentries and inodes. That the opposite remains true is not guaranteed.
