d_splice_alias() callers expect it to either stash the inode reference into a new alias, or drop the inode reference. That makes it possible to just return d_splice_alias() result from ->lookup() instance, without any extra housekeeping required. Unfortunately, that should include the failure exits. If d_splice_alias() returns an error, it leaves the dentry it has been given negative and thus it *must* drop the inode reference. Easily fixed, but it goes way back and will need backporting.
