Subject: [PATCH] rtmutex: Fix the preprocessor logic with normal #ifdef #else #endif
Date: Mon, 10 Sep 2018 21:46:38 -0400 [thread overview]
Message-ID: <20180910214638.55926030@vmware.local.home> (raw)
From: Steven Rostedt (VMware) <rostedt@goodmis.org>
Merging v4.14.68 into v4.14-rt I tripped over a conflict in the
rtmutex.c code. There I found that we had:
#ifdef CONFIG_DEBUG_LOCK_ALLOC
[..]
#endif
#ifndef CONFIG_DEBUG_LOCK_ALLOC
[..]
#endif
Really this should be:
#ifdef CONFIG_DEBUG_LOCK_ALLOC
[..]
#else
[..]
#endif
This cleans up that logic.
