Merge tag 'trace-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
- Remove unused ftrace_direct_funcs variables
- Fix a possible NULL pointer dereference race in eventfs
- Update do_div() usage in trace event benchmark test
- Speedup direct function registration with asynchronous RCU callback.
The synchronization was done in the registration code and this caused
delays when registering direct callbacks. Move the freeing to a
call_rcu() that will prevent delaying of the registering.
- Replace simple_strtoul() usage with kstrtoul()
