Proof step 12 from proof readpage-get (
previous step
)
# buf = VFS_PAGE_SIZE, files[m] = mkfile(m3, md0, m4, content), m ∈ files, n ∈ content ⊦ content[n] = getpage(n, content)
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 13
:
⊦ getpage(n, content) = (n ∈ content ⊃ content[n];zeropage)
Rule argument
spec: afs-stream name: getpage seq: ⊦ getpage(n, content) = (n ∈ content ⊃ content[n];zeropage) subst: [content, n] → [content, n] flags: <all paths>
Additional information
Used terms: content, n
