qla4xxx_is_eh_active(9)

💅 qla4xxx_is_eh_active(9) — like, the Kernel API Manual but make it make sense

okay so bestie, welcome to the glow-up of a kernel API page from the Kernel API Manual ✨ this one's about qla4xxx_is_eh_active, and it's honestly giving "tiny function, big main character energy" 🎀

---

🌸 NAME 🌸

qla4xxx_is_eh_active — bestie, it literally checks if the error handler is running 💅 no cap, that's the whole job.

---

✨ SYNOPSIS ✨

bool qla4xxx_is_eh_active (struct Scsi_Host *shost );

like… it returns a bool, it takes a struct Scsi_Host *, that's it, that's the vibe 🦋

---

🎀 ARGUMENTS 🎀

• shost — pointer to the SCSI Host struct 🫶 literally just a pointer, hand it over and let the function cook.

---

💖 DESCRIPTION 💖

so this routine finds out whether a reset of the host was called during an EH scenario, or whether it came from some application — like sg_reset, for example 🌈 that's the whole tea, periodt.

ngl this is a "which lane did this come from" check, not a magic reset button — it's just asking the question, bestie 🙈
