Not the "best" example, according to Samuel's feedback and the diff
below.  How about something like:

ERROR: space required after that ',' (ctx:VxV)
#10: FILE: arch/riscv/include/asm/barrier.h:28:
+#define __smp_mb()	RISCV_FENCE(rw,rw)

This would go away per my comment to 1/4.

  Don't forget to keep people who spent time reviewing, or providing
  feedback to, your patch in the loop/in Cc: in your next iterations;
  they might be the only people who will be able to provide feedback
  /suggestions/help in your future life.
