Proof step 35 from proof fsync-dirs (previous step)

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 ⊦ [let ino = inode.ino, asynced0 = ?, asynced = ? in {icache_check_inode#(ino, icache; asynced0, asynced, err); if err = ESUCCESS ∧ asynced0 ∧ asynced then icache_get#(ino, icache; asynced0, inode, err); if err = ESUCCESS ∧ asynced0 ∧ asynced then afs_write_inode#(inode; err, dirs, files; asynced1); if err = ESUCCESS then {asynced := false; icache_set_status#(ino, asynced; err, icache)}}; if err = ESUCCESS then afs_fsync#(inode, false, dirs, files; ; asynced2, err)] (dirs = dirs0)

Heuristic symbolic execution applied rule let right

And obtained the following new goals

Proof step 36:
