submit_bio_wait(9)

💖 NAME 💖

submit_bio_wait — submit a bio, and wait until it completes. Welcome to the submit_bio_wait(9) page in the Kernel API Manual, bestie ✨

✨ SYNOPSIS ✨

int submit_bio_wait (struct bio *bio );

🌸 ARGUMENTS 🌸

• bio — the struct bio that describes the I/O 🫶

🦋 DESCRIPTION 🦋

Okay so this one is literally a simple wrapper around submit_bio. It returns 0 on success, or the error from bio_endio on failure. No cap. 💅

⚠️ WARNING: unlike how submit_bio is usually used, this function does not result in the bio reference being consumed. The caller must drop the reference on their own. This is important, bestie — do not let that ref just vibe there unattended 😭
