From e90a2857c666913258528ce96decc43c749bbf95 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Tue, 17 Jul 2007 13:36:07 +0200 Subject: [S390] Simplify stack trace. sparse gives us a few of these: stacktrace.c:69:38: warning: incorrect type in argument 2 (different signedness) stacktrace.c:69:38: expected unsigned int *skip Just get rid of the 'skip' argument since it is contained in the struct stack_trace that gets passed anyway.
