STRUCT MSU_BUFFER_ENTRY(9)

💅 struct msu_buffer_entry(9) 💅

okay so bestie, this is straight from the Kernel API Manual, and it's literally the internal bookkeeping situation for MSU buffers. no cap, it's giving "tiny struct, important job" energy ✨

🎀 NAME 🎀

struct msu_buffer_entry — internal MSU buffer bookkeeping 🫶

✨ SYNOPSIS ✨

struct msu_buffer_entry {
    struct list_head        entry;
    const struct msu_buffer *mbuf;
    struct module           *owner;
 };

💖 Members 💖

• entry — the link to msu_buffer_list, slay 🔗
• mbuf — the MSU buffer object itself, main character energy 💅
• owner — the module that provides this MSU buffer 👑
