Make __d_materialise_dentry() set the materialised dentry name correctly by flipping the arguments to switch_names(). switch_names() is lazy: if both names are internal to their dentries, it'll overwrite that of the first dentry with that of the second, and won't update that of the second. In the case of __d_materialise_dentry(), the second is an already extant anonymous dentry that we want to insert into the tree in place of the dentry we just looked up[*]. However, the dentry we just looked up carries the name we actually want to use. [*] This is used by NFS to join a mount of a subtree into a mount of a tree nearer the root when the two meet, where both mounts share a superblock and thus a set of dentries.
