💅 bvec_set_folio(9) — Kernel API Manual ✨

Okay bestie, welcome to bvec_set_folio(9) from the Kernel API Manual. This is the function that initializes a bvec based off a struct folio. Lowkey iconic setup energy. 🫶

🌸 NAME 🌸

bvec_set_folio — initialize a bvec based off a struct folio

✨ SYNOPSIS ✨

void bvec_set_folio (struct bio_vec *bv , struct folio *folio , size_t
len , size_t offset );

🎀 ARGUMENTS 🎀

• bv — bvec to initialize. This is the main character getting set up. 💖
• folio — folio the bvec should point to. It's giving "this is your assigned folio, bestie." 🎯
• len — length of the bvec. An actual length, not a vibe. 📏
• offset — offset into the folio. Like, where in the folio we're hanging out. 🌸
