#     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"
#     
#     * tag 'trace-v5.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
#       tracing: Initialize iter->seq after zeroing in tracing_read_pipe()
#       tracing/hwlat: Don't ignore outer-loop duration when calculating max_latency
#       tracing/hwlat: Report total time spent in all NMIs during the sample
#       recordmcount: Fix nop_mcount() function
#       tracing: Do not create tracefs files if tracefs lockdown is in effect
#       tracing: Add locked_down checks to the open calls of files created for tracefs
#       tracing: Add tracing_check_open_get_tr()
#       tracing: Have trace events system open call tracing_open_generic_tr()
#       tracing: Get trace_array reference for available_tracers files
#       ftrace: Get a reference counter for the trace_array on filter files
#       tracefs: Revert ccbd54ff54e8 ("tracefs: Restrict tracefs when the kernel is locked down")
