Subject: [PATCH] seq_file: remove redundant assignment of index to m->index
Date: Sat, 10 Feb 2018 23:59:14 +0800	[thread overview]
Message-ID: <CAErzpmu5o+tLJyY9GqkFEOn=KSs0q9pevCBWcvzpxDyV9RiC_Q@mail.gmail.com> (raw)

There are two redundant assignments in the traverse() function, because
the while loop will break after these two assignments, and after that
the variable index will be assigned to m->index again.
