okay bestie, this page is from the Kernel API Manual and it’s about one very specific lil helper. it’s giving “small function, big main character energy” ✨ no cap.

✨ NAME ✨

fm10k_mbx_head_add — determine new head value with added offset 💅

🎀 SYNOPSIS 🎀

u16 fm10k_mbx_head_add (struct fm10k_mbx_info *mbx , u16 offset );

💅 ARGUMENTS 💅

• mbx — pointer to mailbox 💌
• offset — length to add to head offset 🎀

🌸 DESCRIPTION 🌸

okay so here’s the tea: this function takes the local head index and recomputes it for a given length added as an offset. that’s the whole job, bestie — local head index in, recomputed for that added length, done. 🔥
