bvec_set_page(9)

💖 bvec_set_page — NAME 💖

okay so bestie, bvec_set_page is literally the glow-up ritual for a bvec: it initializes a bvec based off a struct page. that's it, that's the whole vibe. iconic behaviour, no notes. ✨

This page lives in the Kernel API Manual btw — that's the manual name, folded in right here at the top so you never have to wonder where you are. 🫶

✨ SYNOPSIS ✨

void bvec_set_page (struct bio_vec *bv , struct page *page , unsigned
int len , unsigned int offset );

like, look at that signature. it's giving "I take four things and I return void." main character energy fr fr. 💅

---

🎀 ARGUMENTS 🎀

• bv — the bvec you're initializing, bestie. this is the one getting set up, so hand it over and let it shine. 💖
• page — the struct page your bvec should point to. that's its whole target, its person, its roman empire. 🎯
• len — the length of the bvec. how much we're working with, no cap. 📏
• offset — the offset into the page. like, where in the page we're starting. lowkey important. 📍

real talk: all four of these are required, and the return type is void — you get nothing back, you just get the bvec set. that's the deal. 💀
