[PATCH] eCryptfs: dput() lower d_parent on rename

[Michael Halcrow <mhalcrow@us.ibm.com>]

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.
