STRUCT BATADV_HASHTABLE(9)

💖 struct batadv_hashtable(9) 💖

okay so bestie, welcome to the Kernel API Manual page for struct batadv_hashtable(9) — yes that's the whole title, yes it's a mouthful, no we are not shortening it, iykyk 🫶

✨ NAME ✨

struct batadv_hashtable — a wrapper of a simple hlist based hashtable. that's it, that's the vibe: it's the little cozy shell around a hashtable, no cap 🎀

🌸 SYNOPSIS 🌸

struct batadv_hashtable {
    struct hlist_head *table;
    spinlock_t *list_locks;
    u32 size;
    atomic_t generation;
 };

like, look at her. four members, zero drama, main character energy 👑

🦋 Members 🦋

• table — the hashtable itself, with the buckets. the actual buckets, the place where things live 🪣
• list_locks — a spinlock for each hash list entry. one lock per entry, keeping everything from getting messy ✨
• size — size of the hashtable, obviously. she's a u32, she knows her measurements 💅
• generation — the current (generation) sequence number. it's an atomic_t, so she's tracking generations atomically, periodt 🔥
