memzero_bvec(9)

💖 NAME 💖

memzero_bvec(9) — zero all data in a bvec. This is from the Kernel API Manual, and yes bestie, it's giving “tiny but important kernel helper” energy. ✨

🌸 SYNOPSIS 🌸

void memzero_bvec (struct bio_vec *bvec );

🎀 ARGUMENTS 🎀

• bvec — the bvec to zero. This is the thing getting zeroed out, periodt. 🫶

💅 DESCRIPTION 💅

Okay so the whole vibe: memzero_bvec zeroes all the data in a bvec. But there is a rule, and it is not optional: it must be called on single-page bvecs only. Single-page. Only. No multi-page chaos, no guessing, no “maybe it’ll work” energy. 😭 This is a hard requirement, so respect it fr fr.
