#     Merge tag 'trace-v4.20-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull more tracing fixes from Steven Rostedt:
#      "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"
