89 		  specifies the number of poll-mode queues. If the IO has HIPRI flag,
90 		  the block-layer will send the IO via the poll-mode queue.
91 		  For fast network and device the polling is faster than interrupt-base
96 		  Set -1 if you want to set it as the number of CPUs
97 		  By default rnbd client creates only irq-mode queues.
99 		  NOTICE: MUST make a unique session for a device using the poll-mode queues.

112 		points to /sys/block/<dev-name>. The last part of the symlink destination
113 		is the same as the device name.  By extracting the last part of the
114 		path the path to the device /dev/<dev-name> can be build.

125 Description:	For each device mapped on the client a new symbolic link is created as
126 		/sys/class/rnbd-client/ctl/devices/<device_id>@<session_name>, which points
128 		The <device_id> of each device is created as follows:
130 		- If the 'device_path' provided during mapping contains slashes ("/"),
131 		  they are replaced by exclamation mark ("!") and used as as the
132 		  <device_id>. Otherwise, the <device_id> will be the same as the
