Manfred Spraul 2ec55f8024 ipc/sem.c: avoid ipc_rcu_putref for failed ipc_addid() ... Loosely based on a patch from Kees Cook <keescook@chromium.org>: - id and retval can be merged - if ipc_addid() fails, then use call_rcu() directly. The difference is that call_rcu is used for failed ipc_addid() calls, to continue to guaranteed an rcu delay for security_sem_free().
