Hi, This series is the result of the discussion with Linus around ipc subsystem initialization and how it behaves with error return when calling rhashtable_init()[1]. Instead of caring about the error or calling the infamous BUG_ON, Linus suggested we guarantee the rhashtable allocation. First two patches modify rhashtable_init() to just return 0, future patches I guess can update more callers. patch 3 is a nit I found while reading the code and just makes use kvmalloc_array(). patch 4+5 remove some ipc hacks we no longer need. patch 6 updates the rhashtable test module. Trivial. Please consider for v4.18. Thanks!
