From 62230e0d702f613e2f93e9c3ffd2893b36eff2db Mon Sep 17 00:00:00 2001 From: Chandan Rajendra Date: Wed, 12 Dec 2018 15:20:11 +0530 Subject: f2fs: use IS_ENCRYPTED() to check encryption status This commit removes the f2fs specific f2fs_encrypted_inode() and makes use of the generic IS_ENCRYPTED() macro to check for the encryption status of an inode.
