Attention is currently required from: plaisthos.
Hello plaisthos,
I'd like you to do a code review.
Please visit
http://gerrit.openvpn.net/c/openvpn/+/1083?usp=email
to review the following change.
Change subject: reliable: Move gc_arena inside reliable_print_ids
......................................................................
reliable: Move gc_arena inside reliable_print_ids
There was no user that actually used it for
anything else. But there were some previous
users that generated a now useless gc_arena.
While looking through the code, modernize
the loop variable usage.
