From 4edbd2f79a95ac608155bf518ea7253c8a0a61fe Mon Sep 17 00:00:00 2001 From: Richard Yao Date: Sun, 7 Jul 2013 11:54:51 -0400 Subject: [PATCH] Remove zio_alloc_arena We declare zio_alloc_arena using extern, but it does not appear to exist anywhere in the code. This permits undefined behavior, so lets remove it.
