From 07c4cc1cdaa08fcb6c0275dd7be49eae37260169 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Thu, 23 Oct 2008 09:33:04 -0400 Subject: ftrace: disable dynamic ftrace for all archs that use daemon The ftrace daemon is complex and can cause nasty races if something goes wrong. Since it affects all of the kernel, this patch disables dynamic ftrace from any arch that depends on the daemon. Until the archs are ported over to the new MCOUNT_RECORD method, I am disabling dynamic ftrace from them. Note: I am leaving in the arch//kernel/ftrace.c code alone since that can be used when the arch is ported to MCOUNT_RECORD. To port the arch to MCOUNT_RECORD, the scripts/recordmcount.pl needs to be updated. I will make that easier to do for 2.6.29. For 28, we will keep the archs disabled.
