From 1e80ad712f69a34d1e3c556d1d674d04b266ad40 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Thu, 11 Jan 2018 23:30:08 -0500 Subject: fscrypt: remove fscrypt_fname_usr_to_disk() fscrypt_fname_usr_to_disk() sounded very generic but was actually only used to encrypt symlinks. Remove it now that all filesystems have been switched over to fscrypt_encrypt_symlink().
