_ctl_eventenable(9)

💖 _ctl_eventenable(9) — main handler for MPT3EVENTENABLE 💖

okay bestie, welcome to the Kernel API Manual page for _ctl_eventenable(9). the way that this function is literally the main handler for the MPT3EVENTENABLE opcode? iconic. no cap.

---

✨ NAME ✨

_ctl_eventenable — main handler for MPT3EVENTENABLE opcode. that's the assignment, and she understood it 💅

---

🦋 SYNOPSIS 🦋

here's the exact signature, character for character, because we do not play about copy-paste:

long _ctl_eventenable (struct MPT3SAS_ADAPTER *ioc , void __user *arg );

---

🎀 ARGUMENTS 🎀

two little besties walk into the function:

• ioc — per adapter object. the per-adapter object in question. main character energy, honestly 🫶
• arg — user space buffer containing ioctl content. that's her whole job. periodt 💖

---

🌈 SEE ALSO 🌈

okay the cross-ref list is long and honestly kind of iconic, so buckle up. the kernel file lore starts at ./drivers/scsi/mpt3sas/mpt3sas_ctl.c, and then we have all these besties:
