bfq_weight_to_ioprio(9)

🎀 NAME — bfq_weight_to_ioprio(9) 🎀

okay so bestie, welcome to the Kernel API Manual page for bfq_weight_to_ioprio(9). its whole job? calc an ioprio from a weight. that’s the assignment, and it ate 💅✨

✨ SYNOPSIS ✨

unsigned short bfq_weight_to_ioprio (int weight );

🍓 ARGUMENTS 🍓

• weight — the weight value to convert. literally the weight value to convert, no extra lore 🫶

🦋 DESCRIPTION 🦋

so here’s the vibe: to preserve as much as possible the old only-ioprio user interface, 0 is used as an escape ioprio value for weights that are (numerically) equal to or larger than IOPRIO_NR_LEVELS * BFQ_WEIGHT_CONVERSION_COEFF. like, it’s keeping the old UI alive as much as possible, and 0 is the escape-hatch value for those bigger weights 💖

bestie, remember: 0 is being used as an escape ioprio value here — not just some random zero. 😭
