mpi3mr_enable_logdata(9)

💖 NAME 💖

okay so this is the mpi3mr_enable_logdata(9) page from the Kernel API Manual, and the whole main-character job here is: Handler for log data enable 💅✨

---

✨ SYNOPSIS ✨

long mpi3mr_enable_logdata (struct mpi3mr_ioc *mrioc , struct bsg_job
       *job );

---

🫶 ARGUMENTS 🫶

• mrioc — the adapter instance reference, bestie 🦋
• job — the BSG job reference, periodt 💫

---

🎀 DESCRIPTION 🎀

OKAY so this function enables log data caching in the driver if it’s not already enabled — no cap, it handles that vibe. Then it returns the maximum number of log data entries that can be cached in the driver. That’s literally the whole flex 💅🔥

---

🔥 RETURN 🔥

0 on success, and proper error codes on failure 😭👑

slay when it’s 0; when it’s not, those error codes are giving “please read me” energy 💀
