SVC_FIND_XPRT(9) Linux Networking SVC_FIND_XPRT(9)NAME
svc_find_xprt - find an RPC transport instance
struct svc_xprt * svc_find_xprt(struct svc_serv * serv, const char * xcl_name, struct net * net, const sa_family_t af,
const unsigned short port);
pointer to svc_serv to search
C string containing transport's class name
owner net pointer
Address family of transport's local address
transport's IP port number
Return the transport instance pointer for the endpoint accepting connections/peer traffic from the specified transport class, address
family and port.
Specifying 0 for the address family or port is effectively a wild-card, and will result in matching the first transport in the service's
list that has a matching class name.

FC_REMOTE_PORT_ADD(9) SCSI mid layer FC_REMOTE_PORT_ADD(9)NAME
fc_remote_port_add - notify fc transport of the existence of a remote FC port.
struct fc_rport * fc_remote_port_add(struct Scsi_Host * shost, int channel, struct fc_rport_identifiers * ids);
scsi host the remote port is connected to.
Channel on shost port connected to.
The world wide names, fc address, and FC4 port roles for the remote port.
The LLDD calls this routine to notify the transport of the existence of a remote port. The LLDD provides the unique identifiers (wwpn,wwn)
of the port, it's FC address (port_id), and the FC4 roles that are active for the port.
For ports that are FCP targets (aka scsi targets), the FC transport maintains consistent target id bindings on behalf of the LLDD. A
consistent target id binding is an assignment of a target id to a remote port identifier, which persists while the scsi host is attached.
The remote port can disappear, then later reappear, and it's target id assignment remains the same. This allows for shifts in FC addressing
(if binding by wwpn or wwnn) with no apparent changes to the scsi subsystem which is based on scsi host number and target id values.
Bindings are only valid during the attachment of the scsi host. If the host detaches, then later re-attaches, target id bindings may
This routine is responsible for returning a remote port structure. The routine will search the list of remote ports it maintains internally
on behalf of consistent target id mappings. If found, the remote port structure will be reused. Otherwise, a new remote port structure will
Whenever a remote port is allocated, a new fc_remote_port class device is created.
Should not be called from interrupt context.
This routine assumes no locks are held on entry.
