ata_scsi_change_queue_depth(9)

🌸 NAME 🌸

ata_scsi_change_queue_depth — SCSI callback for queue depth config 💅

okay so this is the ata_scsi_change_queue_depth(9) page from the Kernel API Manual, and it is literally about one SCSI callback handling queue-depth config. slay.

✨ SYNOPSIS ✨

int ata_scsi_change_queue_depth (struct scsi_device *sdev , int
       queue_depth );

🫶 ARGUMENTS 🫶

• sdev — the SCSI device whose queue depth is getting configured, bestie.
• queue_depth — the new queue depth. that is the number we are setting.

💖 DESCRIPTION 💖

This is the libata standard hostt->change_queue_depth callback. no cap. SCSI calls into this callback when a user tries to set the queue depth via sysfs. it is giving “sysfs says jump, callback asks how high” 🦋.

LOCKING: SCSI layer (we don't care) 😌

🌈 RETURN 🌈

Newly configured queue depth. that is it, that is the return 💫.
