-        d_splice_alias will use any existing IS_ROOT dentry, but it will

-	  should never see such an alias unless the filesystem is
-	  corrupted somehow (for example, if two on-disk directory
-	  entries refer to the same directory.)
-	d_materialise_unique will attempt to move any dentry.  This is
-	  appropriate for distributed filesystems, where finding a
-	  directory other than where we last cached it may be a normal
-	  consequence of concurrent operations on other hosts.
-      Both functions return NULL when the passed-in dentry is used,
