STRUCT NETCONS_USERDATA(9)

🎀 struct netcons_userdata(9) 🎀

okay bestie, welcome to the Kernel API Manual page for struct netcons_userdata(9) — manual name folded right in here so we can get straight to the group chat. 💖

✨ NAME ✨

struct netcons_userdata — the formatted userdata payload of a target. That's it, that's the main character. 👑

🌸 SYNOPSIS 🌸

struct netcons_userdata {
    struct rcu_head         rcu;
    size_t length;
    char data[];
 };

• rcu — the struct rcu_head bit used to free the payload after a grace period. Very "wait for it" energy. ✨
• length — length of data, excluding the NUL terminator. The NUL is literally not invited to the count. 💅
• data — the formatted " key=value0 entries, NUL terminated. Yes, that quote and key=value0 are exactly how it shows up here. 🎀

💜 Description 💜

It's immutable once published — periodt. So the transmit path never observes data and length disagreeing. No cap, the consistency stays iconic. 💅
