It would probably work to put it earlier: It calls handle_mounts() to check and handle mount points, in which a new struct path is created containing a counted reference to the new dentry and a reference to the new vfsmount, which is only counted if it is different from the previous vfsmount.

So sentence is: Then if there is a symbolic link, step_into() calls pick_link() to deal with it, otherwise it installs the new struct path into the struct nameidata, and drops the unneeded references.
