RCU_INIT_POINTER() returns a value that is never used, and which should be abolished due to terminal ugliness: q = RCU_INIT_POINTER(global_p, p); However, there are two uses that cannot be handled by a do-while formulation because they do gcc-style initialization: RCU_INIT_POINTER(.real_cred, &init_cred), RCU_INIT_POINTER(.cred, &init_cred), This usage is clever, but not necessarily the nicest approach. This commit therefore creates an RCU_POINTER_INITIALIZER() macro that is specifically designed for gcc-style initialization. Signed-off-by: Paul E.
