#     Merge tag 'trace-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
#     
#     Pull tracing updates from Steven Rostedt:
#     
#      - Addition of faultable tracepoints
#     
#        There's a tracepoint attached to both a system call entry and exit.
#        This location is known to allow page faults. The tracepoints are
#        called under an rcu_read_lock() which does not allow faults that can
#        sleep. This limits the ability of tracepoint handlers to page fault
#        in user space system call parameters. Now these tracepoints have been
#        made "faultable", allowing the callbacks to fault in user space
#        parameters and record them.
#     
#        Note, only the infrastructure has been implemented. The consumers
#        (perf, ftrace, BPF) now need to have their code modified to allow
#        faults.
#     
#      - Fix up of BPF code for the tracepoint faultable logic
#     
#      - Update tracepoints to use the new static branch API
#     
#      - Remove trace_*_rcuidle() variants and the SRCU protection they used
#     
#      - Remove unused TRACE_EVENT_FL_FILTERED logic
#     
#      - Replace strncpy() with strscpy() and memcpy()
#     
#      - Use replace per_cpu_ptr(smp_processor_id()) with this_cpu_ptr()
#     
#      - Fix perf events to not duplicate samples when tracing is enabled
#     
#      - Replace atomic64_add_return(1, counter) with
#        atomic64_inc_return(counter)
#     
#      - Make stack trace buffer 4K instead of PAGE_SIZE
#     
#      - Remove TRACE_FLAG_IRQS_NOSUPPORT flag as it was never used
#     
#      - Get the true return address for function tracer when function graph
#        tracer is also running.
#     
#        When function_graph trace is running along with function tracer, the
#        parent function of the function tracer sometimes is
#        "return_to_handler", which is the function graph trampoline to record
#        the exit of the function. Use existing logic that calls into the
#        fgraph infrastructure to find the real return address.
#     
#      - Remove (un)regfunc pointers out of tracepoint structure
#     
#      - Added last minute bug fix for setting pending modules in stack
#        function filter.
#     
#          echo "write*:mod:ext3" > /sys/kernel/tracing/stack_trace_filter
#     
#        Would cause a kernel NULL dereference.
#     
#      - Minor clean ups
