Subject: [PATCH v2 0/6] tracing/kprobes: Cleanup with guard and __free

Hi,

Here is the 2nd version of the series to fix and cleanup probe events in
ftrace with __free().
Fix [2/6] according to Oleg's comment to check the argument and add
cleanup.h, update [3/6] to apply it cleanly on probes/for-next, and fix 
[5/6] to assign NULL to 'tk' instead of using no_free_ptr() after
registering it successfully to avoid __must_check_fn warning.

Thanks,

---
