      scsi: qla2xxx: Fix system crash while triggering FW dump · be37aa4b
      Michael Hernandez 提交于
      This patch fixes system hang/crash while firmware dump is attempted with
      Block MQ enabled in qla2xxx driver. Fix is to remove check in fw dump
      template entries for existing request and response queues so that full
      buffer size is calculated during template size calculation.
      
      Following stack trace is seen during firmware dump capture process
