STRUCT SRPT_TPG(9)

okay bestie, welcome to the struct srpt_tpg(9) page from the Kernel API Manual — it’s giving “tiny struct, very specific job” energy ✨

🎀 NAME 🎀

struct srpt_tpg — information about a single “target portal group” 💅

🌸 SYNOPSIS 🌸

       struct srpt_tpg {
           struct list_head        entry;
           struct srpt_port_id     *sport_id;
           struct se_portal_group  tpg;
        };

🦋 MEMBERS 🦋

okay so here are the fields, and yes, every one matters 🫶

• entry — Entry in sport_id->tpg_list.
• sport_id — Port name this TPG is associated with.
• tpg — LIO TPG data structure.

🌸 DESCRIPTION 🌸

Zero or more target portal groups are associated with each port name (srpt_port_id). With each TPG, an ACL list is associated. That’s the whole story, bestie — multiple TPGs can hang out under one port name, and every TPG has an ACL list riding with it 💖.
