mpi3mr_bsg_repost_hdb(9)

💅 mpi3mr_bsg_repost_hdb(9) 💅

okay so bestie, welcome to the Kernel API Manual entry for mpi3mr_bsg_repost_hdb — yeah it's a mouthful, we know, but it's lowkey iconic once you get the vibe ✨

---

🌸 NAME 🌸

mpi3mr_bsg_repost_hdb — Re-post HDB 🫶 that's literally it, that's the whole name, short and sweet

---

🦋 SYNOPSIS 🦋

long mpi3mr_bsg_repost_hdb (struct mpi3mr_ioc *mrioc , struct bsg_job
*job );

like, it takes two things and gives you back a long, no cap 💀

---

🎀 ARGUMENTS 🎀

• mrioc — your adapter instance reference 💖 this is the main character of the whole operation
• job — the BSG job pointer, aka the little task that's asking for the thing 🧚

---

👑 DESCRIPTION 👑

okay so here's the tea ☕ — this function goes and retrieves the HDB descriptor that corresponds to a given buffer type. and if that HDB is currently in released status, then it goes ahead and posts the HDB with the firmware. that's the whole move, fr fr 💅

not me emphasizing the "if" — the posting only happens when the HDB is in released status, so don't go expecting it to fire every single time, bestie 🙈

---

⭐ RETURN ⭐

• 0 on success 🥳
• and proper error codes on failure 😭 (slay for structured error handling honestly)
