sysctl extern cleanup: rtmutex
Extern declarations in sysctl.c should be moved to their own header file, and then include them in relavant .c files. Move max_lock_depth extern declaration to linux/rtmutex.h Signed-off-by: Dave Young <hidave.darkstar@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
