idpf_chk_linearize(9)

📦 version 7.3.1, in nixpkgs unstable

💅 idpf_chk_linearize — a whole manual page, bestie

okay so real talk, this one is from the Kernel API Manual and it is literally about checking whether a packet is doing too much. stay with me 🫶

✨ NAME ✨

idpf_chk_linearize — the little function that checks if your skb is out here exceeding the max descriptors per packet 😭 no cap, that's the whole job.

🌸 SYNOPSIS 🌸

bool idpf_chk_linearize (const struct sk_buff *skb , unsigned int
       max_bufs , unsigned int count );

it returns a bool, she takes three args, and she is very serious about her job 💅

🎀 ARGUMENTS 🎀

  • skb — the send buffer itself, the main character of this whole situation 👑
  • max_bufs — the absolute ceiling on scatter gather buffers for a single packet, like the velvet rope at the club 🚫
  • count — how many buffers this particular packet actually needs, so we can compare vibes ✨

🦋 DESCRIPTION 🦋

so the whole point: make sure we don't exceed the maximum scatter gather buffers for a single packet. that's it. that's the function. 🎯

and before you come for her — the TSO case has been handled earlier from idpf_features_check, so don't @ her about it, she already knows 💁‍♀️

⭐ RETURN ⭐

  • true — the skb exceeds max descriptors per packet (too much, bestie, too much 💀)
  • false — nope, she's fine, everything's within budget 💖

ngl, that's a lot of cross references. she's popular. she's booked and busy. 💅✨

and that's the whole page, bestie — this lil cutie lives in ./drivers/net/ethernet/intel/idpf, dated October 2026, and she ate, no crumbs, periodt 💖🦋
