Hi,

This is the v2 of the series to fix eprobes and cleanup kprobes and probe
events in ftrace to use guard() and scoped_guard() instead of pairs of mutex
locks.
In this version I fixed mixing of gurad and goto in the same function by
using scoped_guard.

Some locks are still not using guard(). We need some more work to complete.

Thanks,
