From c46fff2a3b29794b35d717b5680a27f31a6a6bc0 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Mon, 24 Feb 2014 16:40:02 +0100 Subject: smp: Rename __smp_call_function_single() to smp_call_function_single_async() The name __smp_call_function_single() doesn't tell much about the properties of this function, especially when compared to smp_call_function_single(). The comments above the implementation are also misleading. The main point of this function is actually not to be able to embed the csd in an object. This is actually a requirement that result from the purpose of this function which is to raise an IPI asynchronously. As such it can be called with interrupts disabled. And this feature comes at the cost of the caller who then needs to serialize the IPIs on this csd. Lets rename the function and enhance the comments so that they reflect these properties.
