#     Merge tag 'trace-v5.2-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing warning fix from Steven Rostedt:
#      "Make the GCC 9 warning for sub struct memset go away.
#     
#       GCC 9 now warns about calling memset() on partial structures when it
#       goes across multiple fields. This adds a helper for the place in
#       tracing that does this type of clearing of a structure"
