From e836818bd9ec580b65d1970e588f9ba892a88f5c Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 12 Apr 2017 12:24:35 +0200 Subject: [PATCH] ecryptfs: Convert to separately allocated bdi Allocate struct backing_dev_info separately instead of embedding it inside the superblock. This unifies handling of bdi among users.
