      rxrpc: Trace call completion · 1bae5d22
      David Howells authored
      Add a tracepoint to track rxrpc calls moving into the completed state and
      to log the completion type and the recorded error value and abort code.

      rxrpc, afs: Use debug_ids rather than pointers in traces · a25e21f0
      David Howells authored
      In rxrpc and afs, use the debug_ids that are monotonically allocated to
      various objects as they're allocated rather than pointers as kernel
      pointers are now hashed making them less useful.  Further, the debug ids
      aren't reused anywhere nearly as quickly.
      
      In addition, allow kernel services that use rxrpc, such as afs, to take
      numbers from the rxrpc counter, assign them to their own call struct and
      pass them in to rxrpc for both client and service calls so that the trace
      lines for each will have the same ID tag.

      annotation buffer for added illumination.

      Merge branch 'sfc-filter-locking' · 5d22d47b

      ====================
      sfc: rework locking around filter management
      
      The use of a spinlock to protect filter state combined with the need for a
       sleeping operation (MCDI) to apply that state to the NIC (on EF10) led to
       unfixable race conditions, around the handling of filter restoration after
       an MC reboot.
      So, this patch series removes the requirement to be able to modify the SW
       filter table from atomic context, by using a workqueue to request
       asynchronous filter operations (which are needed for ARFS).  Then, the
       filter table locks are changed to mutexes, replacing the dance of spinlocks
       and 'busy' flags.  Also, a mutex is added to protect the RSS context state,
       since otherwise a similar race is possible around restoring that after an
       MC reboot.  While we're at it, fix a couple of other related bugs.

      The FLOW_RSS flag was causing us to insert UDP filters when TCP was wanted.
