      tracing: Place trace_pid_list logic into abstract functions · 6954e415
      Steven Rostedt (VMware) authored
      Instead of having the logic that does trace_pid_list open coded, wrap it in
      abstract functions. This will allow a rewrite of the logic that implements
      the trace_pid_list without affecting the users.
      
      Note, this causes a change in behavior. Every time a pid is written into
      the set_*_pid file, it creates a new list and uses RCU to update it. If
      pid_max is lowered, but there was a pid currently in the list that was
      higher than pid_max, those pids will now be removed on updating the list.
      The old behavior kept that from happening.
      
      The rewrite of the pid_list logic will no longer depend on pid_max,
      and will return the old behavior.

      Pull io_uring fixes from Jens Axboe:
       "This one looks a bit bigger than it is, but that's mainly because 2/3
        of it is enabling IORING_OP_CLOSE to close direct file descriptors.
      
        We've had a few folks using them and finding it confusing that the way
        to close them is through using -1 for file update, this just brings
        API symmetry for direct descriptors. Hence I think we should just do
        this now and have a better API for 5.15 release. There's some room for
        de-duplicating the close code, but we're leaving that for the next
