Merge tag 'trace-v4.4-rc4-4' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull ftrace fix from Steven Rostedt:
"PeiyangX Qiu reported that if a module fails to load between calling
ftrace_module_init() and do_init_module() that the allocations made in
ftrace_module_init() will not be freed, resulting in a memory leak.
The solution is to call ftrace_release_mod() on the failing module in
the fail path befor do_init_module() is called. This will remove any
allocations made for that module, and nothing if ftrace_module_init()
wasn't called yet for that module.
Note, once do_init_module() is called, the MODULE_GOING notifiers are
called for the failed module, which calls into the ftrace code to do
the proper clean up (basically calling ftrace_release_mod())"
