[PATCH 0/2] tracing: Fix config dependency and trigger parser

From: Masami Hiramatsu

Hi,

These are some fixes which I found recentry on ftrace.

- Since the boot-time tracing synthetic event feature is decoupled
from trigger recenty, it should use CONFIG_SYNTH_EVENT.
- The parser of event trigger seems rejecting some redundant
spaces. But it is hard users to find the wrong point. Such
spaces should be accepted.

BTW, I also found the trigger parser accepts some inputs which
may not correctly formatted, e.g.

# echo "traceon 1" > events/ftrace/print/trigger

(from the document, it must be "traceon:1")
But I think this does not decrease the usability.

Thank you,

---
