Proof step 147 from proof inv-writepage (previous step)

# buf = VFS_PAGE_SIZE, err = ESUCCESS, 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 ⊦ ⟪if err = ESUCCESS then pcache_set#(m, pageno, buf, true; err, pcache)⟫ (pcache-cons(pcache, dirs, files) ∧ synced(dirs, icache, pcache))

Heuristic symbolic execution applied rule if positive right

And obtained the following new goals
