/**
* scst_suspend_activity() - Globally suspend SCSI command processing.
* scst_suspend_activity() - globally suspend any activity
*
* Wait until any ongoing SCSI commands have finished and suspend processing
* of new SCSI commands. If the argument "interruptible" is set to true,
* returns after either SCST_SUSPENDING_TIMEOUT elapsed or if interrupted by a
* signal. Returns zero upon success or a negative error code upon failure.
* Description:
* Globally suspends any activity and doesn't return, until there are any
* active commands (state after SCST_CMD_STATE_INIT). If "interruptible"
* is true, it returns after SCST_SUSPENDING_TIMEOUT or if it was interrupted
* by a signal with the corresponding error status < 0. If "interruptible"
* is false, it will wait virtually forever. On success returns 0.
*
* New arriving commands stay in the suspended state until
* scst_resume_activity() is called.
