And obtained the following new goals

Proof step 92:
files1[ino0] = mkfile(m2, md0, # links(ino0, dirs), content0), files1[ino] = mkfile(m, md, m0, content), afs-cons(dirs, files1), ino ∈ files1, ino0 ∈ files1 ⊦ m = (ino = ino0 ⊃ mkfile(m2, md0, # links(ino0, dirs), content0 upto m2);files1[ino]).size ∧ md = (ino = ino0 ⊃ mkfile(m2, md0, # links(ino0, dirs), content0 upto m2);files1[ino]).meta ∧ m0 = (ino = ino0 ⊃ mkfile(m2, md0, # links(ino0, dirs), content0 upto m2);files1[ino]).nlink ∧ content.stream to m = (ino = ino0 ⊃ mkfile(m2, md0, # links(ino0, dirs), content0 upto m2);files1[ino]).content.stream to (ino = ino0 ⊃ mkfile(m2, md0, # links(ino0, dirs), content0 upto m2);files1[ino]).size, m2 % VFS_PAGE_SIZE ≠ 0 ∧ m2 / VFS_PAGE_SIZE ∈ content0

Rule argument

spec: abstract-file name: elim seq: ⊦ ((m = af.size ∧ md = af.meta) ∧ m0 = af.nlink) ∧ content = af.content ↔ af = mkfile(m, md, m0, content) subst: [af, m, md, m0, content] → [files1[ino], m, md, m0, content]

Additional information

Used simplifier rules: ⊦ ((m = af.size ∧ md = af.meta) ∧ m0 = af.nlink) ∧ content = af.content ↔ af = mkfile(m, md, m0, content); (elim) Used terms: files1[ino], m, md, m0, content
