scsi_restart_operations(9)

💅 scsi_restart_operations(9) — like, the Kernel API Manual, bestie 🎀

okay so picture this: it's scsi_restart_operations(9), from the Kernel API Manual, and she's literally the one who un-jams the whole party. this is the page where your girl gets to explain how we put I/O back on after the error handler went and shut everything down. slay.

✨ NAME ✨

scsi_restart_operations — restart io operations to the specified host. yep, that's the whole vibe. get the host back to work, periodt. 💖

---

🦋 SYNOPSIS 🦋

void scsi_restart_operations (struct Scsi_Host *shost );

---

🌸 ARGUMENTS 🌸

• shost — the Host we are restarting. that's it. that's the argument. she's the main character here and we're bringing her back online. 👑

---

🧚 NOTES 🧚

okay so real talk — when we entered the error handler, we blocked all further i/o to this device. like, all of it, doors locked, sign on the door, no more traffic, sorry bestie. 😭

so now we need to 'reverse' this process. yes, you read that right — we're undoing the block and letting the i/o back in. it's giving glow-up after the crisis. 💅✨

ngl this is the part that matters most: the blocking already happened, and undoing it is the entire job. don't skip this step unless you want your device sitting in silence forever. 🙈
