Merge tag 'trace-v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace

Pull tracing updates from Steven Rostedt:
 "New feature:

   - A new "func-no-repeats" option in tracefs/options directory.

     When set the function tracer will detect if the current function
     being traced is the same as the previous one, and instead of
     recording it, it will keep track of the number of times that the
     function is repeated in a row. And when another function is
     recorded, it will write a new event that shows the function that
     repeated, the number of times it repeated and the time stamp of
     when the last repeated function occurred.

  Enhancements:

   - In order to implement the above "func-no-repeats" option, the ring
     buffer timestamp can now give the accurate timestamp of the event
     as it is being recorded, instead of having to record an absolute
     timestamp for all events. This helps the histogram code which no
     longer needs to waste ring buffer space.

   - New validation logic to make sure all trace events that access
     dereferenced pointers do so in a safe way, and will warn otherwise.

  Fixes:

   - No longer limit the PIDs of tasks that are recorded for
     "saved_cmdlines" to PID_MAX_DEFAULT (32768), as systemd now allows
     for a much larger range. This caused the mapping of PIDs to the
     task names to be dropped for all tasks with a PID greater than
     32768.

   - Change trace_clock_global() to never block. This caused a deadlock.

  Clean ups:

   - Typos, prototype fixes, and removing of duplicate or unused code.

   - Better management of ftrace_page allocations"
