Subject: [PATCH 0/2] ftrace/selftest: Fix ftracetest for non existant config and files

Hi Masami,

I worked a bit more on the one issue that Po-Hsu found, and made it use
tracefs a bit more aggressively. To test this I ran the test on a 3.5
kernel and found another issue, where it failed because set_event_pid
and set_ftrace_pid did not exist.

Can you review these patches. I can take them in my tree, or if Shuah
would like, she can take it in hers (after you give a review).

Thanks!
