blk_mq_start_request(9)

🌸 NAME 🌸

okay so bestie, this page is blk_mq_start_request(9) from the Kernel API Manual, and the whole serve is literally: Start processing a request. no cap, that's the name and the vibe ✨

✨ SYNOPSIS ✨

void blk_mq_start_request (struct request *rq );

🎀 ARGUMENTS 🎀

• rq — Pointer to request to be started. that's the whole argument, bestie: a pointer to the request that's about to get her full attention 💅

🦋 DESCRIPTION 🦋

This is the function device drivers use to notify the block layer that a request is going to be processed now, so the blk layer can do proper initializations such as starting the timeout timer. it's giving “heads-up, she's on her way” energy, and the timeout timer gets its little start moment ⏰✨
