McKenney" , Ingo Molnar , Peter Zijlstra , Thomas Gleixner , Andrew Morton , linux-kernel@vger.kernel.org Cc: Steven Rostedt Subject: [PATCH 1/2] rcu: just rename call_rcu_bh instead of making it a macro Content-Disposition: inline; filename=call_rcu_bh-rename-of-call_rcu.patch Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Seems that I found a box that has a config that passes call_rcu_bh as a function pointer (see net/sctp/sm_make_chunk.c), so declaring the call_rcu_bh has a macro function isn't good enough. This patch makes it just another name of call_rcu for rcupreempt.
