Subject: eCryptfs: dput() lower d_parent on rename
From: Michael Halcrow <mhalcrow@xxxxxxxxxx>
On rename, for both the old and new lower dentry objects, eCryptfs is
missing a dput on the lower parent directory dentry. This patch will
prevent the BUG() at fs/dcache.c:613 from being hit after renaming a file
inside eCryptfs and then doing a umount on the lower filesystem.
