#     Merge tag 'trace-v5.5-rc6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing fixes from Steven Rostedt:
#      "Various tracing fixes:
#     
#        - Fix a function comparison warning for a xen trace event macro
#     
#        - Fix a double perf_event linking to a trace_uprobe_filter for
#          multiple events
#     
#        - Fix suspicious RCU warnings in trace event code for using
#          list_for_each_entry_rcu() when the "_rcu" portion wasn't needed.
#     
#        - Fix a bug in the histogram code when using the same variable
#     
#        - Fix a NULL pointer dereference when tracefs lockdown enabled and
#          calling trace_set_default_clock()
#     
#        - A fix to a bug found with the double perf_event linking patch"
