🌸 NAME 🌸

struct genl_small_ops — generic netlink operations (small version). it's giving "genl_ops but on a budget" and honestly? we stan a space-saving icon. ✨

---

🦋 SYNOPSIS 🦋

struct genl_small_ops {
    int (*doit)(struct sk_buff *skb, struct genl_info *info);
    int (*dumpit)(struct sk_buff *skb, struct netlink_callback *cb);
    u8 cmd;
    u8 internal_flags;
    u8 flags;
    u8 validate;
 };

like look at her. six fields. zero bloat. main character energy fr fr. 💖

👑 Members 👑

• doit — the standard command callback. your everyday "do the thing" function, no cap. 🔥
• dumpit — the callback for dumpers. yeah, the dumping squad gets their own hook. 💀
• cmd — the command identifier. it's a u8, so keep it cute and small. 🎀
• internal_flags — flags used by the family. the family's own little private business, iykyk. 🙈
• flags — the GENL_* flags (specifically GENL_ADMIN_PERM or GENL_UNS_ADMIN_PERM). permission vibes only. 🔐
• validate — validation flags from enum genl_validate_flags. she checks things. she validates. we love a responsible queen. ✨

🌈 Description 🌈

so like, this is a cut-down version of struct genl_ops — for the users who literally don't need most of the ancillary infra and just want to save space. 🫶

that's it. that's the whole pitch. less stuff, smaller struct, same genl energy. periodt. 💅
