target/tcm_fc: Rename structs and list members for clarity
Rename struct ft_lport_acl to ft_lport_wwn. "acl" is associated with something different in LIO terms. Really, ft_lport_wwn is the fabric-specific wrapper for the struct se_wwn. Rename "lacl" local variables to "ft_wwn" as well. Rename list_heads used as list members to make it clear they're nodes, not heads. Rename lport_node to ft_wwn_node. Rename ft_lport_list to ft_wwn_list Signed-off-by: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
