[PATCH 0/2] [GIT PULL] tracing: More fixes for 4.20

From: Steven Rostedt
Date: Thu Nov 29 2018 - 22:19:11 EST


This includes two more fixes:

- Change idx variable in DO_TRACE macro to __idx to avoid name conflicts.
A kvm event had "idx" as a parameter and it confused the macro.

- Fix a race where interrupts would be traced when set_graph_function was set.
The previous patch set increased a race window that tricked the function graph
tracer to think it should trace interrupts when it really should not have.
The bug has been there before, but was seldom hit. Only the last patch series
made it more common.

Note, this is on top of a previous git pull that I have submitted:
