bio_associate_blkg(9)

💖 NAME 💖

okay so bestie, welcome to bio_associate_blkg(9) from the Kernel API Manual 🫶 this one is literally about associating a bio with a blkg, no cap.

bio_associate_blkg - associate a bio with a blkg ✨

🌸 SYNOPSIS 🌸

void bio_associate_blkg (struct bio *bio );

🎀 ARGUMENTS 🎀

• bio — target bio 👑

🦋 DESCRIPTION 🦋

Associate bio with the blkg found from the bio's css and request_queue. If one is not found, bio_lookup_blkg creates the blkg ✨.

If a blkg is already associated, the css is reused and the association is redone, because the request_queue may have changed 👀.
