From ff1c8fac88ab8e7dac65236b277908c7c5c7ab09 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Wed, 3 Jul 2013 15:05:37 -0700 Subject: init: remove permanent string buffer from do_one_initcall() do_one_initcall() uses a 64 byte string buffer to save a message. This buffer is declared static and is only used at boot up and when a module is loaded. As 64 bytes is very small, and this function has very limited scope, there's no reason to waste permanent memory with this string and not just simply put it on the stack.
