zfcp_status_read_refill - refill the long running status_read_requests : ptr to struct zfcp_adapter for which the buffers should be refilled
Returns: 0 on success, 1 otherwise
if there are 16 or more status_read requests missing an adapter_reopen is triggered

zfcp_unit_enqueue - enqueue unit to unit list of a port. : pointer to port where unit is added : FCP LUN of unit to be enqueued Returns: 0 success
Sets up some unit internal structures and creates sysfs entry.
Definition at line 119 of file zfcp_unit.c.
zfcp_unit_find - Find and return zfcp_unit with specified FCP LUN : zfcp_port where to look for the unit : 64 Bit FCP LUN used to identify the zfcp_unit
If zfcp_unit is found, a reference is acquired that has to be released later.
Returns: Pointer to the zfcp_unit, or NULL if there is no zfcp_unit with the specified FCP LUN.
Definition at line 89 of file zfcp_unit.c.
zfcp_unit_queue_scsi_scan - Register configured units on port : The zfcp_port where to register units
After opening a port, all units configured on this port have to be registered with the SCSI midlayer. This function should be called after calling fc_remote_port_add, so that the fc_rport is already ONLINE and the call to scsi_scan_target runs the same way as the call in the FC transport class.

zfcp_unit_sdev - Return SCSI device for zfcp_unit : The zfcp_unit where to get the SCSI device for
Returns: scsi_device pointer on success, NULL if there is no SCSI device for this zfcp_unit
On success, the caller also holds a reference to the SCSI device that must be released with scsi_device_put.
