#     Merge tag 'trace-v5.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull more tracing updates from Steven Rostedt:
#      "Two fixes and one patch that was missed:
#     
#       Fixes:
#     
#        - Missing __print_hex_dump undef for processing new function in trace
#          events
#     
#        - Stop WARN_ON messages when lockdown disables tracing on boot up
#     
#       Enhancement:
#     
#        - Debug option to inject trace events from userspace (for rasdaemon)"
#     
#     The enhancement has its own config option and is non invasive. It's been
#     discussed for sever months and should have been added to my original
#     push, but I never pulled it into my queue.
#     
#     * tag 'trace-v5.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
#       tracing: Do not create directories if lockdown is in affect
#       tracing: Introduce trace event injection
#       tracing: Fix __print_hex_dump scope
