scmd_eh_abort_handler(9)

👑 scmd_eh_abort_handler 💅

okay so bestie, welcome to the Kernel API Manual, section 9 — this is where we handle command aborts and honestly? it's giving main character energy in the SCSI error handler. let's get into it 🎀

---

✨ NAME ✨

scmd_eh_abort_handler — literally the function that handles command aborts. that's it, that's the vibe. 🦋

---

🫶 SYNOPSIS 🫶

void scmd_eh_abort_handler (struct work_struct *work );

yes queen, it returns void, we're not about that return-value life here ✨

---

🌸 ARGUMENTS 🌸

• work — the command to be aborted. like, the actual thing you're cancelling. go off, work 💅

---

🔥 NOTE (read this one fr fr) 🔥

okay so this function must be called only for a command that has timed out. no cap. do not come in here with a fresh little command that's doing fine, that's not what we're doing today. 😭

here's the why, because the why is iconic: because the block layer marks a request as complete before it calls scsi_timeout, a .scsi_done call from the LLD for a command that has timed out do not have any effect. so yeah — that whole callback is just out here having zero impact, living its truth, doing nothing. 💀

hence it is safe to call scsi_finish_command from this function. 🫶 slay. safe. periodt.
