Subject: [GIT PULL] tracing probes: Updates for 6.2


Linus,

As Masami is still working on getting his gpg key working with signed tags
and such, he asked me to send his pull request on his behalf until he gets
that straighten out.

Trace probes updates for 6.2:

- New "symstr" type for dynamic events that writes the name of the
  function+offset into the ring buffer and not just the address

- Prevent kernel symbol processing on addresses in user space probes
  (uprobes).

- And minor fixes and clean ups


Please pull the latest trace-probes-v6.2 tree, which can be found at:
