34 I.e. "clt_hostname-srv_hostname" could be a natural choice.
70 directory and an entry in /sys/class/rnbd-client/ctl/devices
75 the following parameter "dev_search_path=/run/rnbd-devs/%SESSNAME%",
77 will try to open: /run/rnbd-devs/blya/sda.
81 mapped as "ro" read-only or "rw" read-write. The server allows
82 a device to be exported in rw mode only once. The "migration"
83 access mode has to be specified if a second mapping in read-write
84 mode is desired.
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.
