zfcp_scsi_sysfs_host_reset(9)

✨ zfcp_scsi_sysfs_host_reset — the Kernel API Manual page, but make it make sense ✨

okay so bestie, this is zfcp_scsi_sysfs_host_reset(9) from the Kernel API Manual, and it's literally the function that supports the scsi_host sysfs attribute host_reset. That's it. That's the whole vibe. Let's get into it 🫶

---

🌸 SYNOPSIS 🌸

int zfcp_scsi_sysfs_host_reset (struct Scsi_Host *shost , int reset_type );

like, she takes two things and gives you back an int. iconic behavior honestly 💅

---

🎀 ARGUMENTS 🎀

• shost — Pointer to the Scsi_Host you want to perform the action on. That's your main character right there, she's the one getting reset ✨
• reset_type — so here's the tea: we support SCSI_ADAPTER_RESET but not SCSI_FIRMWARE_RESET. Read that again. We do NOT do the firmware one. Not today, not ever 💀

---

🦋 RETURN 🦋

Returns 0 on SCSI_ADAPTER_RESET, and -EOPNOTSUPP otherwise. So basically: adapter reset = slay, anything else = sorry bestie, not supported 🙈

---

💖 DESCRIPTION 💖

This one is similar to zfcp_sysfs_adapter_failed_store. That's the whole note, ngl, it's giving "little sister of a bigger function" energy 😭💜

lowkey reminder: SCSI_FIRMWARE_RESET is not supported here, so don't come for her asking for it. -EOPNOTSUPP will be waiting 😌
