      [SCSI] scsi_dh_alua: Retry the check-condition in case Mode Parameters Changed · 410f02d8
      Moger, Babu authored
      This patch adds a check-condition in scsi_dh_alua handler for a retry.
      Sometimes, I have seen attach failing due to this check-condition with
      following error messages on NetApp E series storage.

      [SCSI] bfa: Implement LUN Masking feature using the SCSI Slave Callouts. · 5b7db7af
      Krishna Gudipati authored
      This patch re-implements LUN Masking feature using SCSI Slave Callouts.  With
      the new design in the slave_alloc entry point; for each new LUN discovered we
      check with our internal LUN Masking config whether to expose or to mask this
      particular LUN. We return -ENXIO (No such device or address) from slave_alloc
      for the LUNs we don't want to be exposed.  We also notify the SCSI mid-layer
      to do a sequential LUN scan rather than REPORT_LUNS based scan if LUN masking
      is enabled on our HBA port, since a -ENXIO from any LUN in REPORT_LUNS based
      scan translates to a scan abort.  This patch also handles the dynamic lun
      masking config change from enable to disable or vice-versa by resetting
      sdev_bflags of LUN 0 appropriately.

      [SCSI] fcoe: remove double check if skb is nonlinear · f1633011
      Robert Love authored
      skb_linearize already has a check for skb_is_nonlinear,
      there is no need to duplicate the check in fcoe.c. This
      patch simply removes the unnecessary check and calls
      skb_linearize unconditionally.

      Manish Rangankar authored
      If ql4xdisablesysfsboot = 0 and sendtargets entry as boot index then
      driver does export sendtarget entries in sysfs but iscsistart does not
      do discovery. So in this case let driver do the discovery and
      login to the targets.

      [SCSI] qla4xxx: Limit the ACB Default Timeout value to 12s · c28eaaca
      Nilesh Javali authored
      A wrong default timeout value programmed in the adapter causes driver
      to wait for that much time while waiting for target discoveries to complete.
      This could add huge delays during the driver load time. To avoid this,
      limit the default timeout value to 12 seconds if the default timeout value
      set in adapter is less than 12 seconds and greater than 120 seconds.

      [SCSI] libcxgbi: do not print a message when memory allocation fails · 00c4a09b
      Thadeu Lima de Souza Cascardo authored
      In alloc_pdu, libcxgbi tries to allocate a skb with GFP_ATOMIC, which
      may potentially fail. When it happens, the current code prints a warning
      When the system is under IO stress, this failure may happen lots of
      times and it usually scares users.
      Instead of printing the warning message, the code now increases the
      tx_dropped statistics for the ethernet interface wich is doing the iscsi
