Proof step 5 from proof write-loop-inv (previous step)

isdir ↔ false, ino1 = n0, write-inv(n0, n1, inode, buf, n, dirs, files0, files1) ⊦ [ino0 := n1; while err = ESUCCESS ∧ ¬ isdir do vfs_write_block#(ino1, inode, buf, ino0, dirs; n, isdir, err, files1, asynced)] write-inv(n0, n1, inode, buf, n, dirs, files0, files1)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
