Proof step 45 from proof fsync-inode-err (previous step)

icache[m] = mkientry(true, inode), err = ESUCCESS, err0 = ESUCCESS, pre-write-inode(inode, dirs, files), m ∈ icache ⊦ [icache_set_status#(m, false; err, icache)] (err = ESUCCESS ∨ ⌊err⌋ ), inode.directory

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 46:
inode.nlink = files[inode.ino].nlink, inode.nsubdirs = 0, icache[m] = mkientry(true, inode), err = ESUCCESS, m ∈ icache, inode.ino ∈ files, ¬ inode.directory ⊦ [icache_set_status#(m, false; err, icache)] (err = ESUCCESS ∨ ⌊err⌋ )
