Proof step 101 from proof truncate-empty (previous step)

files0[ino0] = mkfile(m, md0, # links(ino0, dirs), content0), n = m0 * VFS_PAGE_SIZE + n0, n0 < VFS_PAGE_SIZE, afs-cons(dirs, files0), ino0 ∈ files0 ⊦ [asynced := ?] ((content0 upto n).stream from n = σ⊥), VFS_PAGE_SIZE = 0, n0 ≠ 0 ∧ m0 ∈ content0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 102:
