#     Merge tag 'trace-v5.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing fixes from Steven Rostedt:
#      "A few tracing fixes:
#     
#        - Remove lockdown from tracefs itself and moved it to the trace
#          directory. Have the open functions there do the lockdown checks.
#     
#        - Fix a few races with opening an instance file and the instance
#          being deleted (Discovered during the lockdown updates). Kept
#          separate from the clean up code such that they can be backported to
#          stable easier.
#     
#        - Clean up and consolidated the checks done when opening a trace
#          file, as there were multiple checks that need to be done, and it
#          did not make sense having them done in each open instance.
#     
#        - Fix a regression in the record mcount code.
#     
#        - Small hw_lat detector tracer fixes.
#     
#        - A trace_pipe read fix due to not initializing trace_seq"
