eCryptfs: Invalidate dcache entries when lower i_nlink is zero commit 5556e7e6d30e8e9b5ee51b0e5edd526ee80e5e36 upstream. Consider eCryptfs dcache entries to be stale when the corresponding lower inode's i_nlink count is zero. This solves a problem caused by the lower inode being directly modified, without going through the eCryptfs mount, leaving stale eCryptfs dentries cached and the eCryptfs inode's i_nlink count not being cleared.
