      net/smc: use separate work queues for different worker types · 22ef473d
      Karsten Graul authored
      There are 6 types of workers which exist per smc connection. 3 of them
      are used for listen and handshake processing, another 2 are used for
      close and abort processing and 1 is the tx worker that moves calls to
      sleeping functions into a worker.
      To prevent flooding of the system work queue when many connections are
      opened or closed at the same time (some pattern uperf implements), move
      those workers to one of 3 smc-specific work queues. Two work queues are
      module-global and used for handshake and close workers. The third work
      queue is defined per link group and used by the tx workers that may
      sleep waiting for resources of this link group.
      And in smc_llc_enqueue() queue the llc_event_work work to the system
      prio work queue because its critical that this work is started fast.
