Linus Torvalds 757fa80f4e Tracing updates for 5.14:
- Added option for per CPU threads to the hwlat tracer
 
  - Have hwlat tracer handle hotplug CPUs
 
  - New tracer: osnoise, that detects latency caused by interrupts, softirqs
    and scheduling of other tasks.
 
  - Added timerlat tracer that creates a thread and measures in detail what
    sources of latency it has for wake ups.
 
  - Removed the "success" field of the sched_wakeup trace event.
    This has been hardcoded as "1" since 2015, no tooling should be looking
    at it now. If one exists, we can revert this commit, fix that tool and
    try to remove it again in the future.
 
  - tgid mapping fixed to handle more than PID_MAX_DEFAULT pids/tgids.
 
  - New boot command line option "tp_printk_stop", as tp_printk causes trace
    events to write to console. When user space starts, this can easily live
    lock the system. Having a boot option to stop just after boot up is
    useful to prevent that from happening.
 
  - Have ftrace_dump_on_oops boot command line option take numbers that match
    the numbers shown in /proc/sys/kernel/ftrace_dump_on_oops.
 
  - Bootconfig clean ups, fixes and enhancements.
 
  - New ktest script that tests bootconfig options.
 
  - Add tracepoint_probe_register_may_exist() to register a tracepoint
    without triggering a WARN*() if it already exists. BPF has a path from
    user space that can do this. All other paths are considered a bug.
 
  - Small clean ups and fixes
