#     Merge tag 'trace-v5.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing fixes from Steven Rostedt:
#      "Four small fixes:
#     
#        - Fix a ringbuffer bug for nested events having time go backwards
#     
#        - Fix a config dependency for boot time tracing to depend on
#          synthetic events instead of histograms.
#     
#        - Fix trigger format parsing to handle multiple spaces
#     
#        - Fix bootconfig to handle failures in multiple events"
