#     Merge tag 'trace-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing updates from Steven Rostedt:
#      "No new features this release. Mostly clean ups, restructuring and
#       documentation.
#     
#        - Have ftrace_bug() show ftrace errors before the WARN, as the WARN
#          will reboot the box before the error messages are printed if
#          panic_on_warn is set.
#     
#        - Have traceoff_on_warn disable tracing sooner (before prints)
#     
#        - Write a message to the trace buffer that its being disabled when
#          disable_trace_on_warning() is set.
#     
#        - Separate out synthetic events from histogram code to let it be used
#          by other parts of the kernel.
#     
#        - More documentation on histogram design.
#     
#        - Other small fixes and clean ups"
