If anything, s/path/dentry/, since vfsmnt here will be equal to &mnt->mnt all along.

Too subtle for me.

And is it? Because mnt is from

     mnt = real_mount(path->mnt);

earlier, while vfsmount is plain "path->mnt".

static inline struct mount *real_mount(struct vfsmount *mnt)
{
        return container_of(mnt, struct mount, mnt);
}
