From eae04d25a713304c978d7c45dcab01b0e0811c74 Mon Sep 17 00:00:00 2001 From: Davidlohr Bueso Date: Tue, 21 Aug 2018 22:01:56 -0700 Subject: ipc: simplify ipc initialization Now that we know that rhashtable_init() will not fail, we can get rid of a lot of the unnecessary cleanup paths when the call errored out.
