Proof step 33 from proof fsync-dirs (previous step)

files0[m] = mkfile(m0, md0, m1, content), ¬ asynced3, dirs = dirs0, dirs1 = dirs0, err = ESUCCESS, err0 = ESUCCESS, ino = m, inode = mkinode(m, md, false, m1, 0, m2), inode0 = mkinode(m, md, false, m1, 0, m2), n0 = 0, m ∈ files0 ⊦ [cache_fsync-inode#(; inode, err, dirs, files, icache, asynced1); if err = ESUCCESS then afs_fsync#(inode, asynced3, dirs, files; ; asynced2, err)] (dirs = dirs0), n * VFS_PAGE_SIZE < inode0.size ∧ err = ESUCCESS

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 34:
files0[m] = mkfile(m0, md0, m1, content), dirs = dirs0, err = ESUCCESS, inode = mkinode(m, md, false, m1, 0, m2), m ∈ files0, m2 ≤ n * VFS_PAGE_SIZE ⊦ [cache_fsync-inode#(; inode, err, dirs, files, icache, asynced1); if err = ESUCCESS then afs_fsync#(inode, false, dirs, files; ; asynced2, err)] (dirs = dirs0)

Additional information

Used simplifier rules: ⊦ m < n ↔ ¬ n ≤ m; (ss)% ⊦ mkinode(m, md, boolvar, m0, m1, m2).size = m2; (s)
