scsi_device_resume(9)

💖 scsi_device_resume — Kernel API Manual ✨

okay bestie, welcome to the scsi_device_resume(9) glow-up page 🫶 this is the Kernel API Manual entry and it's lowkey one of the most satisfying little functions in the whole SCSI closet. periodt.

---

🌸 NAME 🌸

scsi_device_resume — like, restart the user-issued commands to a device that got quiesced 👑 it's giving "un-pause the playlist" energy.

---

🦋 SYNOPSIS 🦋

void scsi_device_resume (struct scsi_device *sdev );

that's it. one arg. no cap. ✨

---

🎀 ARGUMENTS 🎀

• sdev — the scsi device to resume 💅 literally the thing you're waking back up. main character.

---

💅 DESCRIPTION 💅

so here's the vibe: this moves the device from quiesced back to running, and restarts the queues. that's the whole gig. the queues were sitting there like 🧍 and now they're back and thriving.

⚠️ okay important, no skipping: this must be called with user context, and it may sleep. like, it's allowed to nap. don't come at it with atomic context energy, it's not that girl. 😭
