scsi_eh_test_devices(9)

💅 scsi_eh_test_devices(9) — Kernel API Manual ✨

💖 NAME 💖

scsi_eh_test_devices — check if devices are responding from error recovery.

---

✨ SYNOPSIS ✨

Okay bestie, here's the exact signature — do not come for the spacing, it's literally giving what it needs to give 💅:

int scsi_eh_test_devices (struct list_head *cmd_list , struct list_head
       *work_q , struct list_head *done_q , int try_stu );

---

🎀 ARGUMENTS 🎀

Four little besties walk into the error-recovery group chat:

• cmd_list — scsi commands in error recovery.
• work_q — queue for commands which still need more error recovery.
• done_q — queue for commands which are finished.
• try_stu — boolean on if a STU command should be tried in addition to TUR.

---

🦋 DESCRIPTION 🦋

The original literally spells it Decription: (not me, bestie 😭), and the tea is: it tests if devices are in a working state. Commands to devices now in a working state are sent to the done_q, while commands to devices which are still failing to respond are returned to the work_q for more processing.

No cap: this is the whole error-recovery vibe check. Working devices get the done_q glow-up ✨, still-failing devices get sent back to work_q for more processing 🔁.
