Merge tag 'trace-v7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull tracing fixes from Steven Rostedt:

 - Fix inverted check of registering the stats for branch tracing

   When calling register_stat_tracer() which returns zero on success and
   negative on error, the callers were checking the return of zero as an
   error and printing a warning message. Because this was just a normal
   printk() message and not a WARN(), it wasn't caught in any testing.

   Fix the check to print the warning message when an error actually
   happens.

 - Fix a typo in a comment in tracepoint.h

 - Limit the size of event probes to 3K in size

   It is possible to create a dynamic event probe via the tracefs system
   that is greater than the max size of an event that the ring buffer
   can hold. This basically causes the event to become useless.

   Limit the size of an event probe to be 3K as that should be large
   enough to handle any dynamic events being created, and fits within
   the PAGE_SIZE sub-buffers of the ring buffer.
