From e6bfeab1c352ae73a19361c038e2a06a58c035db Mon Sep 17 00:00:00 2001 From: John Lo Date: Thu, 4 Jan 2018 16:39:42 -0500 Subject: Unify and cleanup usage of hash_set/unset_mem by various tunnels Move the functions hash_set_key_copy() and hash_unset_key_free() which are dupilicated in various tunnel support code modules to hash.h as hash_set_mem_alloc() and hash_unset_mem_free() to be used by all.
