Proof step 138 from proof fsync-dirs (previous step)

files0[m] = mkfile(m0, md0, m1, content), err = ESUCCESS, m ∈ files0, m2 ≤ n * VFS_PAGE_SIZE, ¬ m ∈ icache ⊦ [icache_set_status#(m, false; err, icache); dirs := dirs0; if err = ESUCCESS then afs_fsync#(mkinode(m, md, false, m1, 0, m2), false, dirs, files; ; asynced2, err)] (dirs = dirs0)

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 139:
asynced ↔ false, files0[m] = mkfile(m0, md0, m1, content), err = ESUCCESS, ino = m, m ∈ files0, m2 ≤ n * VFS_PAGE_SIZE ⊦ [if ino ∈ icache then icache[ino].dirty := asynced else err := EFAIL; dirs := dirs0; if err = ESUCCESS then afs_fsync#(mkinode(m, md, false, m1, 0, m2), false, dirs, files; ; asynced2, err)] (dirs = dirs0), m ∈ icache

Rule argument

pos: right 1

Additional information

Used simplifier rules: icache_set_status#(INO, DIRTY; ERR, ICACHE) {if INO ∈ ICACHE then ICACHE[INO].dirty := DIRTY else ERR := EFAIL};
