🌸 NAME 🌸

batadv_mcast_forw_shrink_align_offset — get new alignment offset 💫

🎀 SYNOPSIS 🎀

short batadv_mcast_forw_shrink_align_offset (unsigned int num_dests_old
, unsigned int num_dests_reduce );

🦋 ARGUMENTS 🦋

  • num_dests_old — the old amount of destination nodes, like, the one that's about to get updated 👑 it's the "before" pic fr fr
  • num_dests_reduce — the number of destinations that were removed 🫠 so how many besties did NOT make the cut

💜 DESCRIPTION 💜

so what does it actually do? it calculates the amount of potential extra alignment offset that's needed to adjust the TVLV padding after the change in destination nodes 🌈

that's it. that's the whole vibe. no cap ✨

🔥 RETURN 🔥

  • 0 — if no change to padding is needed 💅 everything's already iconic, nothing to do
  • 2 — if padding needs to be removed 🧚 so we're trimming, we're decluttering
  • -2 — if padding needs to be added 🌸 okay so now we're ACCESSORIZING, we need more
