Proof step 5 from proof eq-io-readdir (previous step)

⟨afs_readdir#(p_inode, dirs1, files1, asynced0; strings, err)⟩ (strings = strings1 ∧ err = err0), asynced ↔ boolvar0, dirs = dirs1, files = files1, inode = p_inode, strings0 = strings, pre-readdir(inode.ino, dirs, files) ⊦ ⟨{strings0 := dom dirs[inode.ino].entries; err := ESUCCESS} or {choose strings with true in strings0 := strings; fail#(; ; err)}⟩ (strings0 = strings1 ∧ err = err0)

Heuristic symbolic execution applied rule or right

And obtained the following new goals
