Proof step 3 from proof write-loop-0 (previous step)

files = files0, files0 = files1, ino = n, ino0 = n1, ino1 = n0 ⊦ [let isdir = false in while err = ESUCCESS ∧ ¬ isdir do vfs_write_block#(ino1, inode, buf, ino0, dirs; ino, isdir, err, files, asynced)] (ino = 0 → files = files1)

Heuristic symbolic execution applied rule let right

And obtained the following new goals

Proof step 4:
isdir ↔ false, files = files0, files0 = files1, ino = n, ino0 = n1, ino1 = n0 ⊦ [while err = ESUCCESS ∧ ¬ isdir do vfs_write_block#(ino1, inode, buf, ino0, dirs; ino, isdir, err, files, asynced)] (ino = 0 → files = files1)
