Proof step 24 from proof readpage-prepost (previous step)

# buf = VFS_PAGE_SIZE, files[m0] = mkfile(n0, md, # links(m0, dirs), content), n1 < VFS_PAGE_SIZE, n1 < # content[n], F(files -- m0), afs-cons(dirs, files), m0 ∈ files, n ∈ content ⊦ content[n][n1] = (content.stream from n * VFS_PAGE_SIZE)[n1]

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 25:
# buf = VFS_PAGE_SIZE, files[m0] = mkfile(n0, md, # links(m0, dirs), content), n1 < VFS_PAGE_SIZE, F(files -- m0), afs-cons(dirs, files), n ∈ content, m0 ∈ files ⊦ content[n][n1] = (content.stream from n * VFS_PAGE_SIZE)[n1]

Rule argument

Additional information

Used simplifier rules: ⊦ afs-cons(dirs, files) ∧ ino ∈ files ∧ files[ino] = mkfile(m, md, n0, content) ∧ n ∈ content → # content[n] = VFS_PAGE_SIZE; (s)
