From 1453465d074b492d8ba3ab87a06cf4493facaa6e Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Fri, 3 Jul 2009 08:44:07 -0500 Subject: [PATCH] lockdep: RT recursion limit fix commit 3b1dbf9875d464a0d29c3deac45ae3018eee3f16 in tip. OK, I sent this out once before but it must have slipped under the radar. http://lkml.org/lkml/2007/6/28/325 My config fails miserably with lockdep: kernel/lockdep.c: In function 'find_usage_forwards': kernel/lockdep.c:814: error: 'RECURSION_LIMIT' undeclared (first use in this function) kernel/lockdep.c:814: error: (Each undeclared identifier is reported only once kernel/lockdep.c:814: error: for each function it appears in.) kernel/lockdep.c:815: warning: implicit declaration of function 'print_infinite_recursion_bug' kernel/lockdep.c: In function 'find_usage_backwards': kernel/lockdep.c:856: error: 'RECURSION_LIMIT' undeclared (first use in this function) make[1]: *** [kernel/lockdep.o] Error 1 But this patch fixes it nicely.
