💅 qla4xxx_eh_device_reset(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual page for qla4xxx_eh_device_reset — yes that's the whole title, she's long, she's iconic, we move. 🎀

---

🌸 NAME 🌸

qla4xxx_eh_device_reset — the callback for target reset. that's it, that's the vibe. ✨

---

🦋 SYNOPSIS 🦋

int qla4xxx_eh_device_reset (struct scsi_cmnd *cmd );

like, she takes one thing and hands you back an int. simple queen behavior honestly. 💅

---

🍓 ARGUMENTS 🍓

• cmd — Pointer to Linux's SCSI command structure. yeah, that's Linux's SCSI command struct, capital L Linux, it's giving "pointer to the whole situation". 🫶

---

👑 DESCRIPTION 👑

so here's the tea: this routine gets called by the Linux OS when it wants to reset all luns on the specified target. all of them. every single lun. no crumbs. 😭

that's literally the whole job — Linux OS rings her up, she resets all the luns on the target you pointed at, periodt. 🔥

okay and one last thing before you go, bestie — the fine print 💖

this page ships out of the ./drivers/scsi/qla4xxx source tree, dated October 2026, and it's filed under the Kernel API Manual. that's the whole colophon, mwah, go reset some luns responsibly. 🎀✨🦋 iykyk.
