And obtained the following new goals

Proof step 11:
buf = mkbuf(VFS_PAGE_SIZE), err = ESUCCESS, VFS_PAGE_SIZE - (ino2 + ino0) % VFS_PAGE_SIZE ≠ 0, ino1 ≠ ino2 + ino0, m2 ≠ ino2 + ino0, ino2 + ino0 < ino1, ino2 + ino0 < m2 ⊦ [afs_readpage#(mkinode(m, md, boolvar, m0, m1, m2), (ino2 + ino0) / VFS_PAGE_SIZE, dirs, files, asynced; buf, err); if err = ESUCCESS then {buf0 := copy (buf, (ino2 + ino0) % VFS_PAGE_SIZE, buf0, ino0, min(ino1 - ino2 + ino0, VFS_PAGE_SIZE - (ino2 + ino0) % VFS_PAGE_SIZE, m2 - ino2 + ino0)); ino3 := ino0 + min(ino1 - ino2 + ino0, VFS_PAGE_SIZE - (ino2 + ino0) % VFS_PAGE_SIZE, m2 - ino2 + ino0)}] (⌊err⌋ ∨ err = ESUCCESS)
