Proof step 24 from proof read-loop-err (previous step)

VFS_PAGE_SIZE = n0 + (ino2 + ino0) % VFS_PAGE_SIZE, ino1 ≠ ino2 + ino0, m2 ≠ ino2 + ino0, n0 ≠ 0, ino2 + ino0 < ino1, ino2 + ino0 < m2, m ∈ files ⊦ [fail#(; ; err); if err = ESUCCESS then {buf0 := copy(mkbuf(VFS_PAGE_SIZE), (ino2 + ino0) % VFS_PAGE_SIZE, buf0, ino0, min(ino1 - ino2 + ino0, n0, m2 - ino2 + ino0)); ino3 := ino0 + min(ino1 - ino2 + ino0, n0, m2 - ino2 + ino0)}] (⌊err⌋ ∨ err = ESUCCESS)

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 25:
