Proof step 78 from proof fsync-pages-err (
previous step
)
err = ESUCCESS, ino = m, key = datakey(ino, pageno), pageno = n, n * VFS_PAGE_SIZE < m2, key ∈ pcache, err0 = ESUCCESS ∨ ⌊err0⌋ ⊦ [n := n + 1] (err = ESUCCESS ∨ ⌊err⌋ ), true ∧ pcache[key].dirty
Heuristic symbolic execution applied rule assign right
And closed the goal!
