That patch isn't correct since it assumes that all eCryptfs super blocks
are equal if the lower paths (and, ultimately, the lower inode) are
equal. However, the lower path is only one of many properties of an
eCryptfs superblock. For example, the second mount may have been
configured to use a different file encryption key.
