| H A D | ftrace.h | diff b0fc494fae96a7089f3651cb451f461c7291244c Mon May 12 14:20:43 CDT 2008 Steven Rostedt <srostedt@redhat.com> ftrace: add ftrace_enabled sysctl to disable mcount function
This patch adds back the sysctl ftrace_enabled. This time it is
defaulted to on, if DYNAMIC_FTRACE is configured. When ftrace_enabled
is disabled, the ftrace function is set to the stub return.
If DYNAMIC_FTRACE is also configured, on ftrace_enabled = 0,
the registered ftrace functions will all be set to jmps, but no more
new calls to ftrace recording (used to find the ftrace calling sites)
will be called.
