      scsi: srp_transport: Move queuecommand() wait code to SCSI core · 669f0441
      Bart Van Assche authored
      Additionally, rename srp_wait_for_queuecommand() into
      scsi_wait_for_queuecommand() and add a comment about the queuecommand()
      call from scsi_send_eh_cmnd().
      
      Note: this patch changes scsi_internal_device_block from a function that
      did not sleep into a function that may sleep. This is fine for all
      callers of this function:
      
      * scsi_internal_device_block() is called from the mpt3sas device while
        that driver holds the ioc->dm_cmds.mutex. This means that the mpt3sas
        driver calls this function from thread context.
      * scsi_target_block() is called by __iscsi_block_session() from
        kernel thread context and with IRQs enabled.
      * The SRP transport code also calls scsi_target_block() from kernel
        thread context while sleeping is allowed.
      * The snic driver also calls scsi_target_block() from a context from
        which sleeping is allowed. The scsi_target_block() call namely occurs
        immediately after a scsi_flush_work() call.
