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].
Ah, these numbers should be updated. So fixed some issues in [3/5] and add trace_fprobe.c update in [5/5]. Thanks,
Thanks,
