      kyber: make trace_block_rq call consistent with documentation · fb7b9b02
      Vincent Fu authored
      The kyber ioscheduler calls trace_block_rq_insert() *after* the request
      is added to the queue but the documentation for trace_block_rq_insert()
      says that the call should be made *before* the request is added to the
      queue.  Move the tracepoint for the kyber ioscheduler so that it is
      consistent with the documentation.

      Linus Torvalds authored
      Pull tracing fixes from Steven Rostedt:
       "Fix tracepoint race between static_call and callback data
      
        As callbacks to a tracepoint are paired with the data that is passed
        in when the callback is registered to the tracepoint, it must have
        that data passed to the callback when the tracepoint is triggered,
        else bad things will happen. To keep the two together, they are both
        assigned to a tracepoint structure and added to an array. The
        tracepoint call site will dereference the structure (via RCU) and call
        the callback in that structure along with the data in that structure.
        This keeps the callback and data tightly coupled.
      
        Because of the overhead that retpolines have on tracepoint callbacks,
        if there's only one callback attached to a tracepoint (a common case),
        then it is called via a static call (code modified to do a direct call
        instead of an indirect call). But to implement this, the data had to
        be decoupled from the callback, as now the callback is implemented via
        a direct call from the static call and not an indirect call from the
        dereferenced structure.
      
        Note, the static call only calls a callback used when there's a single
        callback attached to the tracepoint. If more than one callback is
        attached to the same tracepoint, then the static call will call an
        iterator function that goes back to dereferencing the structure
        keeping the callback and its data tightly coupled again.
      
        Issues can arise when going from 0 callbacks to one, as the static
        call is assigned to the callback, and it must take care that the data
        passed to it is loaded before the static call calls the callback.
        Going from 1 to 2 callbacks is not an issue, as long as the static
        call is updated to the iterator before the tracepoint structure array
        is updated via RCU. Going from 2 to more or back down to 2 is not an
        issue as the iterator can handle all theses cases. But going from 2 to
        1, care must be taken as the static call is now calling a callback and
        the data that is loaded must be the data for that callback.
      
        Care was taken to ensure the callback and data would be in-sync, but
        after a bug was reported, it became clear that not enough was done to
        make sure that was the case. These changes address this.
      
        The first change is to compare the old and new data instead of the old
        and new callback, as it's the data that can corrupt the callback, even
        if the callback is the same (something getting freed).
      
        The next change is to convert these transitions into states, to make
        it easier to know when a synchronization is needed, and to perform
        those synchronizations. The problem with this patch is that it slows
        down disabling all events from under a second, to making it take over
        10 seconds to do the same work. But that is addressed in the final
        patch.
      
        The final patch uses the RCU state functions to keep track of the RCU
        state between the transitions, and only needs to perform the
        synchronization if an RCU synchronization hasn't been done already.
        This brings the performance of disabling all events back to its
        original value. That's because no synchronization is required between
        disabling tracepoints but is required when enabling a tracepoint after
        its been disabled. If an RCU synchronization happens after the
        tracepoint is disabled, and before it is re-enabled, there's no need
        to do the synchronization again.
      
        Both the second and third patch have subtle complexities that they are
        separated into two patches. But because the second patch causes such a
        regression in performance, the third patch adds a "Fixes" tag to the
        second patch, such that the two must be backported together and not
        just the second patch"

      tracepoint: Use rcu get state and cond sync for static call updates · 7b40066c
      Mathieu Desnoyers authored
      State transitions from 1->0->1 and N->2->1 callbacks require RCU
      synchronization. Rather than performing the RCU synchronization every
      time the state change occurs, which is quite slow when many tracepoints
      are registered in batch, instead keep a snapshot of the RCU state on the
      most recent transitions which belong to a chain, and conditionally wait
      for a grace period on the last transition of the chain if one g.p. has
      not elapsed since the last snapshot.
      
      This applies to both RCU and SRCU.
      
      This brings the performance regression caused by commit 231264d6
      ("Fix: tracepoint: static call function vs data state mismatch") back to
      what it was originally.
