From ffcc41829ae043d0830bcd4536812fec7e098d93 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Mon, 9 Oct 2017 12:15:38 -0700 Subject: fscrypt: remove unneeded empty fscrypt_operations structs In the case where a filesystem has been configured without encryption support, there is no longer any need to initialize ->s_cop at all, since none of the methods are ever called.
