From 2d445c3e4a8216cfa9703998124c13250cc13e5e Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Fri, 26 Mar 2021 16:29:31 +0100 Subject: locking/rtmutex: Remove rtmutex deadlock tester leftovers The following debug members of 'struct rtmutex' are unused: - save_state: No users - file,line: Printed if ::name is NULL. This is only used for non-futex locks so ::name is never NULL - magic: Assigned to NULL by rt_mutex_destroy(), no further usage Remove them along with unused inline and macro leftovers related to the long gone deadlock tester.
