Proof step 62:
root[path] = dnode(md, sdt), dirs[m] = mkdir(# entries, md1, # links(m, dirs), m2, entries), ((abs|(root, ROOT_INO, path, m) * abs(dnode(md, sdt), m)))(dirs), root.dir?, dom of < ino6, afs-cons(dirs, files), fids-cons(root, abs-files(files), abs-of(of)), ispath(path, ROOT_INO, m, dirs, files), of-cons(of, dirs, files), pr(user, md1), px-parent(user, path, ROOT_INO, dirs, files), m ∈ dirs, path ∈ root, psynced → asynced ⊦ md1 = md ∧ m2 = # dnode(md, sdt).subdirs ∧ # entries = # sdt
