STRUCT ISER_FR_POOL(9)

💖 NAME 💖

okay bestie, welcome to the Kernel API Manual entry for struct iser_fr_pool(9) — it is literally the connection fast registration pool. that’s the whole vibe: a pool for fastreg stuff, no cap 🫶

✨ SYNOPSIS ✨

here’s the literal struct, copied exactly:

       struct iser_fr_pool {
           struct list_head        list;
           spinlock_t lock;
           int size;
           struct list_head        all_list;
        };

🫶 Members 🫶

• list — list of fastreg descriptors. the lineup, basically 💅
• lock — protects fastreg pool. it’s the bouncer keeping the pool safe 🔒
• size — size of the pool. yes, the actual size. iconic.
• all_list — first and last list members. the ends of the squad 🌈
