From: Steven Rostedt Date: Tue, 11 Nov 2008 04:07:30 +0000 (-0500) Subject: ftrace: prevent ftrace_special from recursion X-Git-Tag: v2.6.29-rc1~586^2~79 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5aa1ba6a6c710e747838a22d798ac97a8b248745;p=pandora-kernel.git ftrace: prevent ftrace_special from recursion Impact: stop ftrace_special from recursion The ftrace_special is used to help debug areas of the kernel. Because of this, if it is put in certain locations, the fact that it allows recursion can become a problem if the kernel developer using does not realize that. This patch changes ftrace_special to not allow recursion into itself to make it more robust. It also changes from preempt disable interrupts disable to prevent any loss of trace entries.
