Merge tag 'trace-v6.18-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull tracing fixes from Steven Rostedt:

 - Check for reader catching up in ring_buffer_map_get_reader()

   If the reader catches up to the writer in the memory mapped ring
   buffer then calling rb_get_reader_page() will return NULL as there's
   no pages left. But this isn't checked for before calling
   rb_get_reader_page() and the return of NULL causes a warning.

   If it is detected that the reader caught up to the writer, then
   simply exit the routine

 - Fix memory leak in histogram create_field_var()

   The couple of the error paths in create_field_var() did not properly
   clean up what was allocated. Make sure everything is freed properly
   on error

 - Fix help message of tools latency_collector

   The help message incorrectly stated that "-t" was the same as
   "--threads" whereas "--threads" is actually represented by "-e"
