From a4f987653241db9fa1f99531b430cebb83f1eae1 Mon Sep 17 00:00:00 2001 From: John Ogness Date: Wed, 3 Mar 2021 11:15:27 +0100 Subject: printk: kmsg_dump: remove _nolock() variants kmsg_dump_rewind() and kmsg_dump_get_line() are lockless, so there is no need for _nolock() variants. Remove these functions and switch all callers of the _nolock() variants. The functions without _nolock() were chosen because they are already exported to kernel modules.
