struct dentry * d_splice_alias (struct inode * inode, struct dentry * dentry);
If inode is a directory and has a 'disconnected' dentry (i.e. IS_ROOT and DCACHE_DISCONNECTED), then d_move that in place of the given dentry and return it, else simply d_add the inode to the dentry and return NULL.
This is (will be) needed in the lookup routine of any filesystem that is exportable (via knfsd) so that we can build dcache paths to directories effectively.
If a dentry was found and moved, then it is returned. Otherwise NULL is returned. This matches the expected return value of ->lookup.
