#     Merge tag 'trace-v5.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing updates from Steven Rostedt:
#     
#      - Added new "bootconfig".
#     
#        This looks for a file appended to initrd to add boot config options,
#        and has been discussed thoroughly at Linux Plumbers.
#     
#        Very useful for adding kprobes at bootup.
#     
#        Only enabled if "bootconfig" is on the real kernel command line.
#     
#      - Created dynamic event creation.
#     
#        Merges common code between creating synthetic events and kprobe
#        events.
#     
#      - Rename perf "ring_buffer" structure to "perf_buffer"
#     
#      - Rename ftrace "ring_buffer" structure to "trace_buffer"
#     
#        Had to rename existing "trace_buffer" to "array_buffer"
#     
#      - Allow trace_printk() to work withing (some) tracing code.
#     
#      - Sort of tracing configs to be a little better organized
#     
#      - Fixed bug where ftrace_graph hash was not being protected properly
#     
#      - Various other small fixes and clean ups
#
