Merge tag 'trace-v4.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fixes from Steven Rostedt:
"Alexei discovered a race condition in modules failing to load that can
cause a ftrace check to trigger and disable ftrace.
This is because of the way modules are registered to ftrace. Their
functions are loaded in the ftrace function tables but set to
"disabled" since they are still in the process of being loaded by the
module. After the module is finished, it calls back into the ftrace
infrastructure to enable it.
Looking deeper into the locations that access all the functions in the
table, I found more locations that should ignore the disabled ones"
* tag 'trace-v4.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
ftrace: Add more checks for FTRACE_FL_DISABLED in processing ip records
ftrace: Ignore FTRACE_FL_DISABLED while walking dyn_ftrace records
