Hi all,

After merging the kthread tree, today's linux-next build (i386
defconfig) failed like this:

/tmp/next/build/kernel/trace/trace.c:820:5: error: no previous prototype for 'tracing_alloc_snapshot' [-Werror=missing-prototypes]
  820 | int tracing_alloc_snapshot(void)
      |     ^~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

Caused by commit

  bade44fe546212 (tracing: Move snapshot code out of trace.c and into trace_snapshot.c)
   
I've left this for today.
