Proof step 17 from proof fsync-inode-err (previous step)

asynced ↔ asynced0, icache[m] = mkientry(true, inode0), asynced0, err = ESUCCESS, ino = m, inode = mkinode(m, md, boolvar, m0, m1, m2), m ∈ icache ⊦ [if ino ∈ icache then {inode := icache[ino].inode; asynced := true} else asynced := false; err := ESUCCESS; if err = ESUCCESS ∧ asynced then afs_write_inode#(inode; err, dirs, files; asynced1); if err = ESUCCESS then {asynced := false; icache_set_status#(m, asynced; err, icache)}] (err = ESUCCESS ∨ ⌊err⌋ )

Heuristic symbolic execution applied rule if positive right

And obtained the following new goals

Proof step 18:
