From 73114b6d28727b3f98b6a673c54c64b2c46ce4f5 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Wed, 2 Dec 2020 18:20:34 -0800 Subject: [PATCH] f2fs: remove f2fs_dir_open() Since encrypted directories can be opened and searched without their key being available, and each readdir and ->lookup() tries to set up the key, trying to set up the key in ->open() too isn't really useful. Just remove it so that directories don't need an ->open() method anymore, and so that we eliminate a use of fscrypt_get_encryption_info() (which I'd like to stop exporting to filesystems).
