[PATCH] eCryptfs: CIFS nlink fixes
When CIFS is the lower filesystem, the old lower dentry needs to be explicitly
dropped from inside eCryptfs to force a revalidate. In addition, when CIFS is
the lower filesystem, the inode attributes need to be copied back up from the
lower inode to the eCryptfs inode on an eCryptfs revalidate.
