#     Merge tag 'trace-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing updates from Steven Rostedt:
#      "New:
#     
#        - The Real Time Linux Analysis (RTLA) tool is added to the tools
#          directory.
#     
#        - Can safely filter on user space pointers with: field.ustring ~
#          "match-string"
#     
#        - eprobes can now be filtered like any other event.
#     
#        - trace_marker(_raw) now uses stream_open() to allow multiple threads
#          to safely write to it. Note, this could possibly break existing
#          user space, but we will not know until we hear about it, and then
#          can revert the change if need be.
#     
#        - New field in events to display when bottom halfs are disabled.
#     
#        - Sorting of the ftrace functions are now done at compile time
#          instead of at bootup.
#     
#       Infrastructure changes to support future efforts:
#     
#        - Added __rel_loc type for trace events. Similar to __data_loc but
#          the offset to the dynamic data is based off of the location of the
#          descriptor and not the beginning of the event. Needed for user
#          defined events.
#     
#        - Some simplification of event trigger code.
#     
#        - Make synthetic events process its callback better to not hinder
#          other event callbacks that are registered. Needed for user defined
#          events.
#     
#       And other small fixes and cleanups"
