scsi_timeout(9)

okay bestie, welcome to scsi_timeout(9) from the Kernel API Manual — this is the timeout function for normal scsi commands, and it's basically the “your request is taking too long” page 💅✨

✨ NAME ✨

scsi_timeout — timeout function for normal scsi commands. That's the whole name section, and honestly it ate 🎀

🎀 SYNOPSIS 🎀

okay so the signature is literally right here, no cap:

enum blk_eh_timer_return scsi_timeout (struct request *req );

🫶 ARGUMENTS 🫶

• req — the request that is timing out. This is the main character of the page, and it is not having a good time 😭

💅 NOTES 💅

okay so about locking: we do not need to lock this. The potential for a race is only in that the normal completion handling might run — but if the normal completion function determines that the timer has already fired, then it mustn't do anything. Like, nothing at all, bestie 🚫✨

🌈 SEE ALSO 🌈
