Proof step 36 from proof fsync-inode-inv (previous step)

files[m1] = mkfile(m5, md1, m6, content0), files[m] = mkfile(m0, md0, # links(m, dirs), content), icache[m] = mkientry(true, mkinode(m1, md, boolvar, m2, m3, m4)), dirs[m1] = mkdir(m7, md2, m8, m9, entries), afs-cons(dirs, files), dcache-cons(dcache, dirs, files), icache-cons(icache, dirs, files), pcache-cons(pcache, dirs, files), synced(dirs, icache, pcache), m ∈ files, m ∈ icache ⊦ m1 ∈ dirs ∧ m2 = m8 ∧ m4 = m7 ∧ m3 = m9 ∧ boolvar, m1 ∈ files ∧ m2 = m6 ∧ m3 = 0 ∧ ¬ boolvar

Proof step 37:
⊦ icache-cons(icache, dirs, files) ↔ (∀ ino. ino ∈ icache → icache[ino].inode.ino = ino ∧ (icache[ino].dirty ⊃ valid-file-inode(icache[ino].inode, dirs, files) ;valid-ino(ino, dirs, files) ∧ valid-inode(icache[ino].inode, dirs, files) ))
Proof step 38:
dirs[m1] = mkdir(m7, md2, m8, m9, entries), icache[m] = mkientry(true, mkinode(m1, md, boolvar, m2, m3, m4)), files[m] = mkfile(m0, md0, # links(m, dirs), content), files[m1] = mkfile(m5, md1, m6, content0), afs-cons(dirs, files), dcache-cons(dcache, dirs, files), pcache-cons(pcache, dirs, files), synced(dirs, icache, pcache), m ∈ icache, m ∈ files, ∀ ino. ino ∈ icache → icache[ino].inode.ino = ino ∧ (icache[ino].dirty ⊃ valid-file-inode(icache[ino].inode, dirs, files);valid-ino(ino, dirs, files) ∧ valid-inode(icache[ino].inode, dirs, files)) ⊦ m1 ∈ files ∧ m2 = m6 ∧ m3 = 0 ∧ ¬ boolvar, m1 ∈ dirs ∧ m2 = m8 ∧ m4 = m7 ∧ m3 = m9 ∧ boolvar
