Proof step 1 from proof inv-readpage (conclusion)

afs-cons(dirs, files), pre-readpage(inode, pageno, buf, dirs, files) ⊦ ⟪afs_readpage#(inode, pageno, dirs, files, asynced; buf, err)⟫ true

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
# buf = VFS_PAGE_SIZE, afs-cons(dirs, files), inode.ino ∈ files ⊦ ⟪afs_readpage#(inode, pageno, dirs, files, asynced; buf, err)⟫ true

Rule argument

Additional information

Used simplifier rules: ⊦ valid-file-ino(ino, dirs, files) ↔ ino ∈ files; (s)%⊦ pre-readpage(inode, n, buf, dirs, files) ↔ valid-file-ino(inode.ino, dirs, files) ∧ # buf = VFS_PAGE_SIZE; (s)
