Proof step 2 from proof inv-readpage (previous step)

fo.inodes?, ro.inodes?, file-node-cons(fs, ri), log-cons(log, fs), orphans-cons(fs, ri, ro), pre-readpage(inode, pageno, buf, fs, ri), replay-cons-strong(fs, ri, ro, fi, fo, log), ri-inj(fi), ri-inj(ri), ubifs-cons(fs, ri, ro, fi, fo, log) ⊦ ⟪aubifs_readpage#(inode, pageno, ri, fi, ro, fo, fs, log, boolvar; buf, err)⟫ true

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
# buf = VFS_PAGE_SIZE, ro.inodes?, fo.inodes?, file-node-cons(fs, ri), log-cons(log, fs), orphans-cons(fs, ri, ro), replay-cons-strong(fs, ri, ro, fi, fo, log), ri-inj(ri), ri-inj(fi), ubifs-cons(fs, ri, ro, fi, fo, log), inodekey(inode.ino) ∈ ri, ¬ fs[ri[inodekey(inode.ino)]].directory ⊦ ⟪aubifs_readpage#(inode, pageno, ri, fi, ro, fo, fs, log, boolvar; buf, err)⟫ true

Rule argument

Additional information

Used simplifier rules: ⊦ valid-file-ino(ino, fs, ri) ↔ inodekey(ino) ∈ ri ∧ ¬ fs[ri[inodekey(ino)]].directory; (s)%⊦ pre-readpage(inode, n, buf, fs, ri) ↔ valid-file-ino(inode.ino, fs, ri) ∧ # buf = VFS_PAGE_SIZE; (s)
