      blk-mq: fix waiting for reserved tags · 5810d903
      Jens Axboe 提交于
      blk_mq_wait_for_tags() is only able to wait for "normal" tags,
      not reserved tags. Pass in which one we should attempt to get
      a tag for, so that waiting for reserved tags will work.
      
      Reserved tags are used for internal commands, which are usually
      serialized. Hence no waiting generally takes place, but we should
      ensure that it actually works if users need that functionality.

      blk-mq: respect rq_affinity · 38535201
      Christoph Hellwig 提交于
      The blk-mq code is using it's own version of the I/O completion affinity
      tunables, which causes a few issues:
      
       - the rq_affinity sysfs file doesn't work for blk-mq devices, even if it
         still is present, thus breaking existing tuning setups.
       - the rq_affinity = 1 mode, which is the defauly for legacy request based
         drivers isn't implemented at all.
       - blk-mq drivers don't implement any completion affinity with the default
         flag settings.
      
      This patches removes the blk-mq ipi_redirect flag and sysfs file, as well
      as the internal BLK_MQ_F_SHOULD_IPI flag and replaces it with code that
      respects the queue-wide rq_affinity flags and also implements the
      rq_affinity = 1 mode.
      
      This means I/O completion affinity can now only be tuned block-queue wide
      instead of per context, which seems more sensible to me anyway.
