#     Merge tag 'trace-v5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing fix from Steven Rostedt:
#      "Fix synthetic event "strcat" overrun
#     
#       New synthetic event code used strcat() and miscalculated the ending,
#       causing the concatenation to write beyond the allocated memory.
#     
#       Instead of using strncat(), the code is switched over to seq_buf which
#       has all the mechanisms in place to protect against writing more than
#       what is allocated, and cleans up the code a bit"
#     
#     * tag 'trace-v5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
#       tracing, synthetic events: Replace buggy strcat() with seq_buf operations
