💖 trace_block_bio_remap(9) 💖

hey bestie, welcome to the Kernel API Manual page for trace_block_bio_remap(9) — we're about to make this kernel thing make sense, no cap 🫶

✨ NAME ✨

trace_block_bio_remap — map request for a logical device to the raw device 💅

🛠️ SYNOPSIS 🛠️

void trace_block_bio_remap (struct bio *bio , dev_t dev , sector_t from
       );

🎀 ARGUMENTS 🎀

• bio — the revised operation. That's the bio in question, bestie.
• dev — the original device for the operation. Like where it started.
• from — the original sector for the operation. The starting sector, not a vibe.

🦋 DESCRIPTION 🦋

Here's the tea: an operation for a logical device has been mapped to the raw block device. That's the entire storyline — logical device → raw block device, and that's it. Periodt. ✨
