📦 version 7.3.1, in nixpkgs unstable

💅 batadv_tt_global_size_dec(9) 💅

okay bestie, so this is a page out of the Kernel API Manual — literally the kernel docs, and yes we're reading them for fun now, that's just who we are 🎀 — and it's all about one lil function in batman-adv called batadv_tt_global_size_dec.

✨ NAME ✨

batadv_tt_global_size_dec — decrease by one the global table size for the given vid

like, that's it. that's the whole job. it's a counter that goes down by exactly one, for one specific vlan id. no cap, some functions are just one (1) little guy doing one (1) little thing and honestly? respect 🫶

🌸 SYNOPSIS 🌸

void batadv_tt_global_size_dec (struct batadv_orig_node *orig_node ,
unsigned short vid );

note the void — she returns nothing, she just does the thing and leaves 💅 no return value to check, no error to handle, she's got main character energy and zero drama.

🦋 ARGUMENTS 🦋

  • orig_node — the originator which global table size has to be decreased. like, this is the node whose bookkeeping we're shaving one (1) off of 🍓
  • vid — the vlan identifier. yes bestie, the vlan matters, that's the whole point — it's an unsigned short, keep it that way 😭

👑 SEE ALSO 👑

okay this is the part where the manpage just dumps the entire translation-table friendship group on you. the kernel file is ./net/batman-adv/translation-table.c and here is every single friend in the group chat, in order, no skips, no cuts, we don't do that here 🔥

bestie, pro tip from your girl: if batadv_tt_global_size_inc exists and batadv_tt_global_size_dec exists and batadv_tt_global_size_mod exists, maybe don't call _dec when you wanted _mod. balance is everything 💀

that's the whole page, bestie, go forth and decrement responsibly 🧚 from ./net/batman-adv, dated October 2026, in the Kernel API Manual — mwah, love u, go read the translation table source 💜🦋✨
