From 68279f9c9f592e75d30a9ba5154a15e0a0b42ae8 Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Wed, 11 Oct 2023 19:55:00 +0300 Subject: treewide: mark stuff as __ro_after_init __read_mostly predates __ro_after_init. Many variables which are marked __read_mostly should have been __ro_after_init from day 1. Also, mark some stuff as "const" and "__init" while I'm at it.
