✨ NAME ✨

like, it's literally in the name. Count. Number of. Integrity scatterlist. Elements. periodt.

🌸 SYNOPSIS 🌸

int blk_rq_count_integrity_sg (struct request_queue *q , struct bio *bio );

so you call it, you hand it a queue and a bio, and it hands you back an int. that's it. that's the whole relationship 💫

🎀 ARGUMENTS 🎀

• q — a request queue. yep. that's the struct. struct request_queue *q. she's the queue in question 👑
• bio — a bio that has integrity metadata attached to it. no integrity metadata? then bestie what are you even doing here 😭

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — this function returns the number of elements required in a scatterlist corresponding to the integrity metadata in a bio.

that's it. that's the whole description. she's short, she's sweet, she knows exactly what she's about. no cap 💅

reminder: the count is for the scatterlist elements that correspond to the integrity metadata in that bio. the bio brings the metadata, the function does the math, you get an int. iconic behaviour honestly 🌈
