Proof step 49 from proof write-loop-err (previous step)

# content[(ino2 + ino0) / VFS_PAGE_SIZE] = VFS_PAGE_SIZE, VFS_PAGE_SIZE = n0 + (ino2 + ino0) % VFS_PAGE_SIZE, files[m] = mkfile(m3, md0, m4, content), min(ino1 - ino2 + ino0, n0) ≠ 0, m ∈ files, (ino2 + ino0) / VFS_PAGE_SIZE ∈ content, (ino2 + ino0) % VFS_PAGE_SIZE + min(ino1 - ino2 + ino0, n0) ≤ VFS_PAGE_SIZE, ino0 + min(ino1 - ino2 + ino0, n0) ≤ # buf0, ino2 + ino0 ≤ ino1 ⊦ [fail#(; ; err); asynced := ?; if err = ESUCCESS then ino3 := ino0 + min(ino1 - ino2 + ino0, n0)] (err = ESUCCESS ∨ ⌊err⌋ )

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 50:
