From 06ed48b7ee0c1b3c1dee6f2c90333109cf7db6ac Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 18 Apr 2016 16:55:37 +0200 Subject: TTY: add __init attribute Add __init attribute on a function that is only called from other __init functions and that is not inlined, at least with gcc version 4.8.4 on an x86 machine with allyesconfig. Currently, the function is put in the .text.unlikely segment. Declaring it as __init will cause it to be put in the .init.text and to disappear after initialization. The result of objdump -x on the function before the change is as follows: 000000000000014c l F .text.unlikely 0000000000000a2e init_r_port And after the change it is as follows: 0000000000000000 l F .init.text 0000000000000a29 init_r_port Done with the help of Coccinelle. The semantic patch checks for local static non-init functions that are called from an __init function and are not called from any other function.
