Axel Rasmussen 6107742d15 tracing: support "bool" type in synthetic trace events ... It's common [1] to define tracepoint fields as "bool" when they contain a true / false value. Currently, defining a synthetic event with a "bool" field yields EINVAL. It's possible to work around this by using e.g. u8 (assuming sizeof(bool) is 1, and bool is unsigned; if either of these properties don't match, you get EINVAL [2]). Supporting "bool" explicitly makes hooking this up easier and more portable for userspace.
