Subject: [PATCH 0/7] [GIT PULL] tracing: Various fixes for v4.18-rc6


Linus,

Various fixes to the tracing infrastructure:

 - Fix double free when the reg() call fails in event_trigger_callback()

 - Fix anomoly of snapshot causing tracing_on flag to change

 - Add selftest to test snapshot and tracing_on affecting each other

 - Fix setting of tracepoint flag on error that prevents probes from
   being deleted.

 - Fix another possible double free that is similar to event_trigger_callback()

 - Quiet a gcc warning of a false positive unused variable

 - Fix crash of partial exposed task->comm to trace events
