      rbd: end I/O the entire obj_request on error · 082a75da
      Ilya Dryomov authored
      When we end I/O struct request with error, we need to pass
      obj_request->length as @nr_bytes so that the entire obj_request worth
      of bytes is completed.  Otherwise block layer ends up confused and we
      trip on
      
          rbd_assert(more ^ (which == img_request->obj_request_count));
      
      in rbd_img_obj_callback() due to more being true no matter what.  We
      already do it in most cases but we are missing some, in particular
      those where we don't even get a chance to submit any obj_requests, due
      to an early -ENOMEM for example.
      
      A number of obj_request->xferred assignments seem to be redundant but
      I haven't touched any of obj_request->xferred stuff to keep this small
      and isolated.

      net: can: xilinx_can: fix extended frame handling · 5793affe
      Jeppe Ledet-Pedersen authored
      Using IDR_SRR in RXFIFO_ID to test for the presence of data is only
      valid for standard frames. For extended frames the bit is always 1 and
      IDR_RTR should be used instead. This patch switches the check to use
      CAN_RTR_FLAG which is correctly set when reading the ID.
      
      The patch also changes the DW1/DW2 to be read unconditionally, since
      this is necessary to remove the frame from the RXFIFO.

      net: fec: Fix RGMII-ID mode · e813bb2b
      Markus Pargmann authored
      RGMII-ID uses an internal delay within the transmitter or receiver. This
      feature is phy specific. The rest of the communication is normal RGMII.
      
      So the fec driver has to check for all RGMII modes, not only
      'PHY_INTERFACE_MODE_RGMII'.

      net/mlx4_en: Schedule napi when RX buffers allocation fails · 07841f9d
      Ido Shamay authored
      When system is out of memory, refilling of RX buffers fails while
      the driver continue to pass the received packets to the kernel stack.
      At some point, when all RX buffers deplete, driver may fall into a
      sleep, and not recover when memory for new RX buffers is once again
      availible. This is because hardware does not have valid descriptors,
      so no interrupt will be generated for the driver to return to work
      in napi context. Fix it by schedule the napi poll function from
      stats_task delayed workqueue, as long as the allocations fail.

      netxen_nic: use spin_[un]lock_bh around tx_clean_lock · c232d8a8
      Tony Camuso authored
      While testing this driver with DEBUG_LOCKDEP and DEBUG_SPINLOCK
      enabled did not produce any traces, it would be more prudent in the
      case of tx_clean_lock to use spin_[un]lock_bh, since this lock is
      manipulated in both the process and softirq contexts.
      
      This patch was tested for functionality and regressions with netperf
      and DEBUG_LOCKDEP and DEBUG_SPINLOCK enabled.
