From 94840e3c802daa1a62985957f36ac48faf8ceedd Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Wed, 22 Feb 2017 13:25:14 -0800 Subject: fscrypt: eliminate ->prepare_context() operation The only use of the ->prepare_context() fscrypt operation was to allow ext4 to evict inline data from the inode before ->set_context(). However, there is no reason why this cannot be done as simply the first step in ->set_context(), and in fact it makes more sense to do it that way because then the policy modes and flags get validated before any real work is done. Therefore, merge ext4_prepare_context() into ext4_set_context(), and remove ->prepare_context().
