Proof step 27 from proof writepage-afs-cons (previous step)

# buf2 = VFS_PAGE_SIZE, files[m] = mkfile(m0, md, m1, content), afs-cons(dirs, files), m ∈ files, ino + n ≤ VFS_PAGE_SIZE, ino0 + n ≤ # buf0 ⊦ afs-cons(dirs, files[m, files[m].content:= content[pageno, copy(buf0, ino0, buf2, ino, n)]])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 28:
# buf2 = VFS_PAGE_SIZE, files[m] = mkfile(m0, md, # links(m, dirs), content), afs-cons(dirs, files), m ∈ files, ino + n ≤ VFS_PAGE_SIZE, ino0 + n ≤ # buf0 ⊦ afs-cons(dirs, files[m, mkfile(m0, md, # links(m, dirs), content[pageno, copy(buf0, ino0, buf2, ino, n)])])

Rule argument

Additional information

Used simplifier rules: ⊦ mkfile(m, md, m0, content).content:= content0 = mkfile(m, md, m0, content0); (s)%afs-cons-file-nlink: ⊦ afs-cons(dirs, files) ∧ ino ∈ files ∧ files[ino] = mkfile(m, md, n, content) → # links(ino, dirs) = n; (forward) from specification afs-base
