Hi,

Here is the 3rd version of the series to fix and cleanup probe events in
ftrace with __free(). I resend this without dynevent and argv_free
parts because it has been sent by Steve[1]. And I updated the version
tag.

In this version, I fixed some issues[5/7] and update DEFINE_FREE() tag
name to specify freeing function name so that reader can understand it
easily[2/7].
Also, I added trace_fprobe cleanup with free[7/7].

Thanks,
