✨ NAME ✨

bio_integrity_alloc — allocate an integrity payload and attach it to a bio 🫶

like, it literally goes and gets the integrity payload, and then it's like "here, this is yours now" to the bio. no cap.

🦋 SYNOPSIS 🦋

struct bio_integrity_payload * bio_integrity_alloc (struct bio *bio ,
gfp_t gfp_mask , unsigned int nr_vecs );

that's the whole signature, copy it exactly, she's iconic like that. ⭐

🎀 ARGUMENTS 🎀

  • bio — the bio you're attaching integrity metadata to 💖 like, this is the main character receiving the gift
  • gfp_mask — the memory allocation mask 🌸 this is how you tell the allocator how to behave, iykyk
  • nr_vecs — the number of integrity metadata scatter-gather elements 🌈 that's your count, bestie, keep it accurate

👑 DESCRIPTION 👑

so here's the tea ☕ — this function prepares a bio for attaching integrity metadata. think of it as setting up the venue before the party 🎉

nr_vecs specifies the maximum number of pages containing integrity metadata that can be attached. that's it, that's the whole limit — it's giving "capacity check" energy. 💀

no frills, no surprises, just a bio getting prepped for its integrity glow-up. ✨
